摘要
本文针对跨断层地下管线的地震破坏特性,设计跨断层地下管线的振动台试验模型。首先根据试验条件,对整个模型体系进行相似比分析,设计了可以模拟走滑断层错动作用的模型土箱;其次对模型材料的物理力学特性进行室内试验,确定模型土的级配曲线和抗剪参数;然后根据管线承受断层作用的数值模拟结果,对传感器进行合理的布置;最后,介绍模型土的成形过程。
Buried pipelines constitutes an important part of the lifeline system of a city.A shaking table test for cross-fault buried pipelines is implemented.The scale relations of the test system are deduced according to the test condition.A container for simulating the movement of a strike-slip fault is designed and manufactured.The parameters of the model material properties are obtained via lab tests.Arrangement of sensors is made according to the response of a pipeline to fault movement calculated by using the finite-element method.The molding process is presented.
