Computer Simulation of Pore-Water Pressure

Abstract:

An appropriate analysis of pore pressure models under irregular loading effects is provided. the model is based on liquefaction test with the constant amplitude loading and pore pressure model, based on the accumulated principle of residual pore pressure, using the differential method: superposition method and optimization method. Using constant amplitude loading liquefied test, and artificial modulation irregular load liquefied test and earthquake wave input dynamic triaxial liquefied test on model, the system has been tested, the result displayed: (1) the model can better simulate the results of constant amplitude loading liquefied test; (2) the model can better describe the trend on artificial modulation irregular load liquefied test results (3) the model can describe pore-pressure growth law under earthquake wave, and also can better analysis on differential pore-pressure under different type of earthquake wave (4) the model has less parameters, can analysis of pore-pressure in real time, easy to use.
