摘要

采用有限元数值计算方法分析了地下浅埋结构的非线性动力响应，得到了结构在不同时刻的动态响应模拟计算数据。该地下浅埋结构由金属壳体和上覆土体共同组成，对于土体和金属壳体分别采用Drucker-Prager和Mohr-Coulomb屈服准则以及弹塑性本构关系，分析其非线性动态位移场和应力场。根据爆炸试验数据，研究了爆炸冲击波随距离和时间的变化过程，并且将其作为作用在结构内部的爆炸荷载。有限元数值模拟结果表明，采用非线性有限元模拟爆炸冲击荷载作用下地下浅埋结构的弹塑性动力响应是有效的，并且证明所设计的地下防护结构是安全的。

Abstract

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.
