Abstract

According to the large-scale shaking table model test results of seismic response features of free field system in saturated soft soil, the freefield nonlinearity dynamical effective stress coupled numerical model of saturated soft soil was established by using OpenSEES based on the u-p formulations of dynamic consolidation equation and effective stress solution method for saturated twophase media. The numerical modeling analysis of the freefield seismic response of saturated soft soil under various test conditions was performed and the calculated results were compared with that of the shaking table test results. Results show that the numerical calculation results are in good agreement with that of the shaking table test and show the similar timecourse changes. Therefore, the validity of mechanical modeling based on OpenSEES computing platform and the shaking table test results were proved each other. The numerical model can reasonably simulate the seismic response characteristics of free field in saturated soft soil, which can provide basis for further establishment of other more complex parameter extrapolation models for soft soil sites.
