The selection of seismic wave, meshing of finite element, input methods of wave load are of a great influence on the accuracy in simulating the earthquake response by time history method. The method of oblique incidence of seismic wave in space which is suitable for seismic analysis of underground cavern is put forward by considering the direction, multifaceted and the consistency of the seismic wave...
Seismic action is the main external factor of affecting the long-term safe operation of the large-scale underground caverns. Strengthening characteristics of materials under high strain rate and damage of surrounding rock under circulating load features are considered. Dynamic constitutive model of rock mass is put forward to analyze seismic on the underground caverns. Explicit central difference...
