This frame serves to specify a type of analysis for calculation of the modulus of subsoil reaction, which is an important input parameter when analyzing a sheeting structure by using the method of dependent pressures.
The frame can take different forms depending on the selected method of calculation:
- standard (option "analyze – Schmitt", "analyze – Chadeisson", "manual iteration", or "automatic iteration")
- input (selecting the option "Input by distribution" opens a table in the frame that allows us to input the values of the modulus of subsoil reaction kh both in front of and behind the structure. For option "Input as a soil parameter" the modulus kh is specified in the "Soils" frame, where the modulus of subsoil reaction is considered either as linear, or as nonlinear - curve)
- pressuremeter PMT (modulus of subsoil reaction kh is calculated from pressuremeter test, or input as a parameter of soil in the "Soils" frame. Then there is specified method of calculation - according to NF P 94-282 or according to Menard)
- Chinese standards (for "m" method is defined horizontal displacement at the ditch bottom vb [mm] and magnitude of modulus A [MN/m3], or option input as a parameter of soil – "c" method, "k" or "m" method)
Frame "Modulus kh" - selection "input by distribution"
Frame "Modulus kh" - selection "pressuremeter Ménard"
Frame "Modulus kh" - selection "Chinese standards"
