英文摘要: Based on the scientific work of the major research plan “the major engineering dynamic response” in the field of anti-seismic of underground structure, the experimental results and the work of theoretical methods and simulation software will be formed integration platform by further research, the seismic failure mechanism of underground structures will be further revealed, and the equivalent inertial effects of overlying soil after shear failure and the shear loading effects of horizontal deformation of lateral soil will be provided. The seismic failure mechanism will be concluded, the standard of the ultimate deformation ability of control component in anti-seismic design of underground structures will be proposed and the simplified anti-seismic analysis methods of underground structures will be further established. The research work will provide scientific supports for safe constructions and operations of underground engineering.
