Hi there
I am trying to model a deep excavation in unsaturated conditions. As I only have suction measurements during dry and wet periods, I have been trying to input then as pore-presure in the user-defined water condition of certain clusters (clay materials next to wall). However, it is not possible to input positive values (suction).
I am not sure if it is the best way of model this, I will appreciate any advise on this.
Regards,
Dear Eduardo,
There are 2 possible ways to model this:
1) Instead of directly specifying the suction, you should specify a degree of saturation. To do so, set the Water Condition to "Unsaturated" and specify the degree of saturation.
2) Choose the correct SWCC for the soil in which you have the suction measurements.
With kind regards,
Dennis Waterman
