基于ABAQUS的埋地管道动力分析前处理

Pretreatment for Dynamic Analysis of Buried Pipeline Based on ABAQUS

利用ABAQUS软件强大功能,研究埋地管道在动力分析前需要的各项数据,进行地应力平衡计算,考虑管道自重的静力分析,以及求解边界的节点面积、节点反力、弹簧阻尼器参数、等效荷载力、节点法力和地震波数据处理,有了这些前期准备工作,才能进行下一步的动力分析运算。通过理顺建模、静力分析与各种数据之间的相互关系,希望能够为其他地震研究工作者提供一定的帮助。

Through the powerful function of ABAQUS software,all kinds of data required for the dynamic analysis of buried pipelines were studied,including the calculation of the geostress balance,the static analysis incorporating the dead weight of pipeline,the nodal area,the nodal reaction force,the parameters of the spring damper,the equivalent load,the nodal normal force and the processing of seismic wave data.With these preliminary preparations,the next dynamic analysis operation can be carried out.By rationalizing the relationship between modeling,static analysis and various data,it was hoped to provide some help to other earthquake researchers.
