Finite element method is applied to calculate nonlinear dynamic responses of underground structure and the data of dynamic responses of structure are available. The structure is consists of steel shell and soil body. The elastic-plastic constitutive model is used to modeling deformation characteristic of soil body and steel shell. Drucker-Prager and Mohr-Coulomb yield criteria are applied to describe the soil body and the steel shell
respectively. The blasting load is determined according to experimental data of air explosion. Calculating results using finite element method show that it is effective to calculate dynamic responses of underground structure acted by blasting loads and the proposed defense structure is safety against explosion loads.
