爆炸模拟地震作用埋地供水管网原型试验

Full scale Test of Buried Water Supply Pipeline Network with Explosion Simulation Earthquake

摘要:

利用土中引爆TNT炸药产生模拟地震波.首次通过试验研究了带有柔性接头球墨铸铁管网的动力响应.详细阐述了试验设计思想与方法，给出了主要试验结果.对试验结果的初步分析表明：试验设计思想合理、有效；接头变形与管网系统结构关系密切；接头变形超过一定界限时，必须考虑接头变形的塑性发展.

Abstract:

The seismic wave is generated by detonating trinitrotoluene (TNT) explosives in the soil, and the dynamic response of nodular cast iron pipeline network with flexible joints is studied. The idea and the method of the test design are introduced in detail and the main test results are presented. A preliminary analysis shows that the test design is reasonable and effective. The joint deformation has a close relationship with the systemic structure of the pipeline network. When the joint deformation is greater than a threshold value, the plastic deformation should be taken into consideration.
