Increasing Strength with Depth
The undrained shear strength cu can be defined as increasing with depth. This is set in the "Add New Soil" dialog, where Strength with depth is set as "linear".
By entering the parameter Kcu, the undrained shear strength will increase with depth according to the following formula:
where: | cu,ref | - | undrained shear strength at the reference depth |
z | - | Depth at which it z is defined cu | |
zref | - | reference depth [m] | |
Kcu | - | gradient of increase |
for: | z > zref | - | cu = cu,ref |
z < zref | cu according to the formula |
