WebMar 10, 2024 · PM4Sand 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, h p0, defines the number of cycles to arrive at the point of liquefaction for a given cyclic stress ratio. Webto calibrate the liquefaction triggering and K effect. shaking is shown in Figure 8. The PM4SAND model consists of 21 secondary parameters. C kaf and h o are the two secondary parameters that need modifications during model calibration. PM4SAND estimateDefault values were set for other secondary parameters.
