Basic Data
This part of the window serves to introduce basic parameters of soils - unit weight, angle of internal friction, and cohesion. The particular values are obtained from a geotechnical survey or from laboratory experiments. If these data are not available, it is possible to exploit the built-in database of soils, which contains values of selected characteristics of soils. The characteristics of rocks are not listed in the database built, these parameters must be defined manually.
The associated theory is described in detail in the chapter "Analyses in program Pile CPT".
For calculation of shaft resistance according to the EN 1997-2, NEN 6743 and LCPC (Bustamante) further needs to specify coefficient reducing the shaft friction αs. For coarse-grained soils - sands and gravels further needs to specify the magnitude of overconsolidation (OCR) and type of grains.
