retaining wall / cohesion value

[profesyonel]

Greetings first. I have a question for those with experience. The cohesion value entered while calculating the retaining wall should be averaged according to the soil classes. I have never seen this value calculated and written in soil studies before. I wanted to calculate it myself, frankly, I did not understand anything from the accounts I looked at on the net. I don't want to calculate with the existing value of 0.65 (since I don't know for which type of soil it is).

Dear Professional, Soil cohesion value (c) is a value that should be determined first in all soil studies, that is, it should be in the report. The c value used in the program is especially effective in the base slip safety of the retaining wall, but the passive soil effect calculated with this c value may not be correct since the filling material with filter properties is usually filled behind the retaining walls. Considering this, it is useful to adjust the installation.
