WebPM4Sand can be regarded as an advanced cyclic loading and liquefaction model. However, it is (still) a two-dimensional model, just like the original. There is a clear procedure to determine the model parameters. The main parameter, hp0, defines the number of cycles to arrive at the point of liquefaction for a given cyclic stress ratio. WebApr 1, 2024 · In addition to the calibration results, a shear strength related index (S u,cs,eq _ Rat in PM4Silt) may better represent the behavior and consistency of fine-grained material such as coal tailings compared to relative density (D r in PM4Sand). Therefore, PM4Silt was selected to model the CT in the seismic stability simulations.
