Effective Stress Analysis

For an effective stress analysis, (c',f') should be provided for the effective Mohr-Coulomb strength intercept and the effective Mohr-Coulomb strength angle.  Excess pore water pressure and water head can be defined in the Advanced option.  Excess pore water pressure due to shear can be assumed to be related to the overburden by the single parameter r.  The overburden does not include surcharge boundary loads.  The pore pressure constant r of a soil type defines a constant pore pressure for any point within the soil described.  Excess pore water pressure can also be defined by water head.  Either or both of these two options for specifying pore pressures may be used, in combination with pore pressure related to a specified piezometric surface, to describe the pore pressure regime.
