【摘要】 利用ANSYS有限元分析软件,建立了埋地管道有限元数值分析模型。对管道坍塌问题进行了静力分析,得到了不同坍塌长度下的管道应力情况和管道的失效长度。通过输入地震波,对不同地震烈度下的地震响应进行了有限元数值仿真计算,得到了在不同地震动荷载作用下管道的应力情况和失效长度,为管道的抗震设计提供理论依据。更多还原

【Abstract】 A finite element numerical analysis model of embedding pipeline is built by using ANSYS finite element analysis program.Then the issue of the pipeline under being collapse is analyzed ,and its stress and the length of pipeline failure are obtained.The seismic response of the finite element model under the action of siesmic waves are simulated in different earthquake intensity,and its stress and the length of pipeline failure under dynamic load of collapse is given,the simulated results provide the important foundation for the earthquake.更多还原
