摘　　要：采用固定边界获取静应力场,再改变此应力场的荷载和边界条件,采用黏弹性边界进行动力分析,通过运用大型通用软件ABAQUS,对几种固定方式管道的有限元数值模拟结果进行比对。结果表明,用ABAQUS计算管土地下结构的动力分析是可行且符合实际的。通过实际算例可以看出,进行管道动力响应分析,可以查找出最有利的管道固定方式,还能找出模型最大应力点,即管道的薄弱位置,为城市辅助决策的制定提供有利依据。Stress field is gained through fixed boundary,load and boundary condition of the stress field are changed,and dynamic analysis is done through the adoption of elastic boundary.Through the application of large-scale general software ABAQUS,the finite element value simulation results of several pipes are compared.The results show that calculation of dynamic analysis of underground structures through ABAQUS is feasible and practical.Through practical calculation,pipeline dynamic response analysis is done to find the optimum pipeline fixed method,and find the maximum stress point of the model,i.e.the weak pipeline,in order to provide beneficial evidence for urban aid decision making.
