Abstract

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 method is used in the solution of wave equation program. The program is proved to be correct through the calculation example by general numerical analysis software.
