Build matrix of layers

The matrix of layers (3D-model of layers of an earth's crust) represents a regular file of values of absolute heights and powers of layers. Power (thickness) of a layer it is distance from the top layer up to the bottom level of a layer in meters. Unlike a matrix of heights in which element one value (absolute height) is presented only, in a matrix of layers the element contains a set of values (absolute height, power of 1-st layer, power of 2-nd layer, …, power of N-th layer). The order of layers arrangement concerning a terrestrial surface is set by a legend and stored in the passport of a matrix. Layers can be degenerate, i.e. accept zero value of power. Negative values of power are inadmissible.

Input data for building a matrix of layers are the legend of a matrix and the database of geological measurements formed by modes «Soil description» and «Bore creating» of tasks «Engineering-geological column». Database of geological measurements includes DBF-tables of the bore-holes description and descriptions of the bores soils.

The name of an input DBF-file of the description of bores is set at setup of the task parameters «Engineering-geological column» in a window Description of bore.

The name of input DBF-file of the bores description is displayed in group Input data of dialog of a matrix creation. At creation of a matrix it is used also the DBF-file of soil description of bores which name is formed of a filename of the description of bores with addition «_layers», for example: bore4.dbf - a file of description of bores, bore4_layers.dbf - a file of soil description of bores.

Example of the contents of DBF-file of bores description bore4.dbf:

At creating matrix of layers the fields are used:

-  NUMBERBORE (bores number);

-  X, Y, H (coordinates of a bore);

-  COUNTLAYER (quantity of bore layers).

Example of the contents of DBF-file of soil description of bores bore4_layers.dbf:

At creating a matrix of layers the fields are used:

-  NUMBERBORE (number of bore);

-  THICKNESS (thickness of a soil layer);

-  KEYSOIL (a key of a soil).

The name of a MTL-file of a created matrix and the size of an element are set in Matrix of layers group.

Set a legend of matrix is called by pressing the button «>> » in the Legend of matrix group.

The file of a legend has IMS extension. After setup of a legend the name of IMS-file is entered into section [GEOLOGY] of an INI-file of the document by LegendFile key. If the file of a legend specified in an INI-file of the document, exists, its contents are displayed in the Legend of matrix group of dialog Build matrix of layers.
