摘　　要：本文在地下结构的震害和岩土非线性动力计算方法研究的基础上,采用数值方法,对某大型地下结构进行了完全非线性地震动力时程分析。并采用二次开发的土体非线性动力本构模型,模拟土在循环荷载作用下的动力特性。This article bases on the exploration of undergro-und structures seismic damage and the rock-soil non-linear dy-namic calculation method, adopts the numerical method to ca-rry on the ful y nonlinear seismic dynamic time-histories ana-lysis for the large underground structure, and uses the soil con-stitutive model nonlinear dynamics of the secondary develop-ment to simulate the soil dynamic characteristics under the eff-ect of cyclic loading.
