Dmt Elab Quick Guide

Select File–New from the menu and the 'New Input Form' window (Figure 2) will appear. It will guide you through the creation of a new .dat file. Decide whether to have a fixed step for the depths Z or to assign Z manually at each depth. Zinitial is the first depth at which you have significant readings. Specify also if you have only A and B Readings or also Reading C.

Figure 2 – New Input Form

Press the Ok button and the Input Data window will appear (Figure 3).

Figure 3 – Input Data

Fill in the form with the Dmt test field data. Click on the Advanced Data button in case you want to specify a different central displacement of the membrane (So and FactorEd) and for changing the zero offsets of the pressure gages (default values are fine for 99 % of the cases).

You may save partial work, but only after having entered at least one valid reading (Save As.. button).

Use the Check Input button to get your data checked and to obtain corrections of possible anomalies of test data.

The Options button visualizes the ‘Options’ window (Figure 4) for setting personalized options of the elaboration and graphical output (explained further on). These settings are volatile and will not alter the .dat file. It is possible to open the ‘Options’ window anytime.

Figure 4 – Options

The Advanced button opens the ‘Advanced Options’ window (Figure 5), where you may change elaboration formulae, and other settings like GammaWater Density and Ifeeler.

Figure 5 – Advanced Options

Only expert users should open the ‘Data Filtering’ window (Figure 6), in which you may specify filtering conditions for ignoring readings.

Figure 6 – Data Filtering

From the ‘Options’ window (Figure 4) you may open the ‘Gamma Manual Assignment’ (Assign Gamma button) and the ‘U Manual Assignment’ (Assign U) windows, where you may override Gamma and U interpretation. Specify these assignments only if you have other independent information on these parameters and when you believe them to be more accurate than the program’s prediction.

Figure 7 – Gamma Manual Assignment

When you have finished with the input data, use the Save As.. button to store it in a .dat file.

After you have saved, the .dat file just created will be elaborated (see next section).

3. Elaboration

You may view the graphical and tabular interpreted results in two ways:

· saving changes after input,

· using the File–Open Group menu and selecting a group of one or more .dat files which you want to elaborate (it is impossible to select files that are not in the same directory).

After a group selection the DMT Elab window will look like the one in Figure 8 (default view is the Data View, see further on).

Figure 8 – Elaboration Data View after a selection of .dat files

On the right side of the toolbar is a combo box, preceded by the label ‘Group of Files’. The visible filename is the current .dat file, while the other elements of the list represent the other .dat files of the selected group.

To decide a different order of the files in the group, press the order button, and the ‘File Order’ window (Figure 9) will appear. You may order the files manually selecting one file at a time and using the arrows for changing their position in the group. Elsewise use the Order by Testname or Order by Filename buttons.

Figure 9 – File Order

On the left side of the toolbar are three buttons: Data, Graph and Tabular. These are shortcuts for the View menu items (except for Catalogue which does not have a shortcut button). Each menu item is used to obtain a different view of the current group data:

a) Data – to display the input data

b) Graph – to display parameter graphs

c) Tabular – to display tabular output of the current selected file

d) Catalogue – to display a short data summary for each test of the group

a) Data View

The Data view has the same visual interface as described for the data input (section 2), but displays the data of the current .dat file. If you modify the data you will not be able to change view until you have saved changes (Save As.. button).

Figure 10 – Data View

b) Tabular view

The Tabular view displays the tabular results of the currently selected .dat file (Figure 11). Readings and interpreted parameters are listed for each Z ( Z = depth or absolute elevation according to the settings in the ‘Options’ window of Figure 4). The corresponding Word document (see tabular in Word Doc Menu section) adds a heading to this listing, containing a legend for the parameters and other data regarding the corresponding .dat file.

Figure 11 –Tabular View

c) Graph View

Figure 12 – Graph View of the classic Composite graph of DMT parameters (Z vs. Id, M, Cu, Kd)

For default this modality displays the classic graph in Dmt elaborations: depth Z vs. Id, M, Cu, Kd. However you may explore many graph combinations throughout the ‘Graph Type’ window (click on Select Graph Type and the window of Figure 13 will appear).

Figure 13 – Graph Type

You may choose to view Composite parameter (Figure 12) or Single Parameter (Figure 14) graphs and, for both of these choices, you may also request to superimpose tests (of the selected group) on the same graph.

Figure 14 – Graph View with Single Parameter graph of DMT M parameter

You may also select a Cross Section graph of a single parameter, so that for each test of the selected group that parameter will be plotted side by side on the same page (Figure 15).

Figure 15 – Graph View with a Cross Section graph of Dmt M parameter

From the ‘Graph Type’ window (Figure 13) you may also specify data points’ visualization (lines, isolated points or connected points) and the label size (use large labels when the graph will be shrinked as for power point presentations or journal articles).

From the ‘Options’ window (Figure 4) you can decide to have Z used as a depth or as an absolute elevation.

Right clicking on the graph lets you copy the image in the Clipboard or save it as a bitmap file.

On the left side of the graph is a frame labeled Scales. The content of this frame varies according to the currently displayed graph:

· is the scale for Z on paper output.

· is the scale for M on paper output

· only for the Cross Section type graphs, the scale for the selected parameter is assigned throughout the maximum value of the parameter and the width of the axis (at which this maximum value will be placed). In this example the scale of M = 120 Mpa / 6.0 cm = 20 Mpa / cm.

· Note – some parameters like Id, Phi and Ud have a fixed non-modifiable scale

· List of Buttons:

· AutoRange – Assigns scales automatically.

· Select Z Window – Opens a window for specifying the Z span window. It is possible to:

· view the full profile or

· a span starting from a given Ztop to the current test’s Zfinal or

· a span starting from a given Ztop to a given Zbottom.

· Vertical Shift – Opens a window for assigning a depth shift for each test (will not affect .dat files, and is present only when tests are superimposed or viewed in Cross Section).

· Edit Labels – Opens a window for assigning labels for the graph (available only when tests are superimposed or viewed in Cross Section).

· AutoDraw – Assigns scales automatically in Cross Section view, updating max parameter value and axis size.

· Represents the number of side to side tests (of the current group of files) that will be drawn on the same page of the Cross Section graphs.

d) Catalogue View

Catalogue is another form of view (rarely used), that may be accessed from the View–Catalogue menu. For each test of the Current Group (or the Selected New Group), a short summary will be displayed. Note that selecting a new group from View–Catalogue–Select New Group does not launch elaboration, so choose this way to create a catalogue of a large number of tests, avoiding to wait for their elaboration.

Figure 16 – Catalogue View

4. Tools Menu

The Tools menu has three submenus:

1. Convert to Free-Z Format –available only in Data View and used for converting the current test with fixed Z to freely assignable Z (shortcut: click right on the input data grid).

2. Change Items to Group –used for applying collective changes of input data to all tests of the group. Clicking on this submenu opens the window of Figure 17. The Value input textbox is white when the values of the selected item are the same for all group tests, gray otherwise. You will be prompted to confirm changes that will alter all the .dat files of the group.

Figure 17 – Collective Changes to Group

3. Language & Units – Opens the ‘Program Settings’ window (Figure 18) for selecting the desired language for graph and tabular output and the desired units to use during data input.

Figure 18 – Program Settings

5. Word Doc Menu

The WordDoc menu is used for creating Word reports:

· Autoreport – generates an automatic report of graphs and tabular output. It contains the classic Dmt parameter graphs and includes also superimposed and Cross Section graphs. Undesired graphs may be canceled.

· Diagnostic Data Draft – generates a list containing the input data and other interpreted parameters. It is useful for checking typing errors after the input of new .dat files.

· Dat File – generates a listing of the .dat file.

· Current Graph – generates the graph currently displayed.

· Tabular – generates a tabular output.

· Catalogue – generates the catalogue of the files in the selected group.

Shortcut buttons labeled ‘Create Word Doc’ for the Data, Tabular and Catalogue view and ‘Partial Word Doc’ for the Graph view, are available for generating the corresponding Word report. The ‘Full Autoreport’ shortcut is present only in the Graph View.

NOTE It is convenient to create at first the automatic report, you can then modify the document directly from Word. To include other Word reports generated from this program, create other reports using the WordDoc Menu (or shortcuts), then use the ‘cut’ and paste’ method for adding them to the automatic report.

6. Uni File

Uni files are used for the settlement analysis program. To generate .uni files:

· click on the File–Create Uni File–Current File menu for creating the .uni file of the currently selected .dat file.

· click on the File–Create Uni File–All Group menu for creating one .uni file for each .dat file of the current group.

The .uni files will be automatically generated in the same directory of the corresponding .dat files.
