摘要

地下管道破坏受到场地岩土条件和断层的制约，如何分析场地条件对地下管道地震破坏的影响，是城市地下管道建设中面临的突出问题。采用ADINA建模的定义体操作，选定合适的体类型，应用布尔操作实现了管道与土体和断层之间的融合，得到地下管道破坏分析的几何模型。通过模型参数选择，确定了岩土性质、管道特性、断层等模型参数，定义了管土摩擦、地震荷载时间函数、断层荷载和约束条件。依据计算结果，分析了管土摩擦、埋深、断层参数以及断层活动性等场地条件对地下管道地震破坏的影响，并给出了结论和工程建议。

Abstract

The damage of buried pipeline is controlled by site condition

such as faults

characteristics of rock and soil. Analyzing the influence of site condition on the damage of buried pipeline under earthquake load is the key of earthquake lifeline engineering. By the operation of defintion body in ADINA

the type of site body is selected

and pipeline body is subtracted from site body by Boolean Body Operators. Therefore

the geometry model is obtained. Through model preferences

parameters of the model are defined

such as the characteristics of rock and soil in site

characteristics of pipeline and faults. Time function of earthquake load and displacement load of faults are applied

initial displacements are defined based on the movement of faults

and pipe-soil friction is considered by contact control in ADINA. According to the calculating results

influence of buried depth

parameters of faults

pipe-soil friction

and faults movement is investigated. Some advice for the protection of buried pipeline under earthquake load is proposed.
