Retaining and cohesion

[saaahin]

Hello, when idecadte is doing a retaining solution, when the cohesion value from the ground survey is entered, the slip verifications on the retaining are not possible, it does not save. soil survey values soil group/class C/Z2 qem=1.7 kg/cm2 internal friction angle 35-45 degrees cohesion 7.7 kg/cm2 bearing coefficient 2040 t/m3 is there a problem with the units?... idecadte cohesion default its value is 0.9 t/m2

Hi, when idecadte is doing a retaining solution, when the cohesion value from the soil study is entered, the slip verification is not possible on the retaining. soil study values soil group/class C/Z2 qem=1.7 kg/cm2 internal friction angle 35-45 degrees cohesion 7.7 kg/cm2 bearing coefficient 2040 t/m3 I wonder if there is a problem with the units?... idecadte cohesion default value is 0.9 t/m2

Hello, If the cohesion value is too large, the moment arm negative, so the moment value may be calculated large.

Hello, if the cohesion value is too large, the moment arm may be negative, and accordingly the moment value may be calculated large. You can solve it without considering the cohesion. (In general practice, it is recommended to ignore the cohesion effect since the ground behind the wall is emptied and refilled.) Good work

Thanks for your attention.. according to my research, the ground is rock... since the cohesion value is calculated as bearing capacity/2 it came out too high... as you said, since the floor behind the wall is emptied and filled, the solution will be more correct without considering the cohesion... Have a good work...
