Terrain - Plane and Polygonal Slip Surface
Two possibilites of terrain input are available it the frame "Terrain". Terrain can be defined by sections of rock slope or it can be defined by coordinates X and Z. This frame contains a table with a list of defined sections of a rock slope or table with list of coordinates of each terrain point. In the program, the slope is always oriented from the left to the right.
The coordinates of the origin - the first point of terrain followed by defined sections - are entered in the upper part of the frame if the method of definition of sections of rock slope (inclination and length) is used.
Each section can be defined by its dip, by the overall length of section, by the horizontal length and height of section of a rock slope. Only two selected values are used while the others are determined by the program automatically (if more than two entry fields are checked than the input and computation are not carried out). Both vertical and horizontal sections as well as overhangs can be represented. Terrain must be defined from the bottom up.
In case of a proper input the program automatically plots the defined section on desktop using dashed line, so that before accepting the defined section by pressing the "Add" button it is possible to check, whether the section is correctly defined.
Frame "Terrain" - Inclination and length
If you use the coordinates for definiton of terrain, the surface of terrain must be defined from bottom up. Adding point is performed in the "New point" dialog window. These points can also be edited on desktop with the help of active objects. Both vertical and horizontal sections as well as overhangs can be represented. The program allows importing points from table data.
