DYNAMIC CONSTITUTIVE MODEL FOR MATERIAL OF ROCKFILL DAMS

摘要：

The recent development in dynamic constitutive models for material of rockfill dams is reviewed and summarized. Their advantages and disadvantages are compared in describing stress-strain relations under various conditions for granular materials. The P-Z constitutive model, which is a kind of the multi-mechanism plastic model based on generalized plasticity, is mainly introduced. It doesnt have to definitely define yield surface and plastic potential surface. Meanwhile, the model can describe the dynamic and static features of sands and clay. Based on the available tests, the determination of the parameters for P-Z model is also given.Then, the shaking table test is carried.
