Seismic Behaviors on CFGRD

The goal structure is the concrete-faced grouted rockfill dam (CFGRD) in Zhoushan of China. Based on the properties non-linearity, the structural interaction and the seismic uncertainty, the dynamic non-linear constitutive model has been established in order to evaluate the seismic safety of the CFGRD as well as its interactive zones. Their dynamic sensibility has also been explored with the dynamic FEM. According to the results of the comprehensive dynamic response field distributions, the rock-bolts family of the CFGRD plays the principal role for the seismic safety.
