土工离心机模拟爆炸及冲击作用的原理及应用

Theory and applications of geotechnical centrifuge modeling of blast and impact

从比较三种模拟爆炸的方式,即现场试验、离心机模拟和数值模拟的优缺点出发,介绍了岩土工程离心机在模拟爆炸及冲击时的基本原理和试验验证,并阐述了各国学者所做的一些研究如地面爆炸对地下隧道及其他建筑结构的影响、离心机模拟大爆破等,最后创造性的提出了对三峡大坝抗爆能力校核的试验方法。

From the three approaches of blasting simulation including advantages and disadvantages of the site tests,centrifugal machine simula-tion and numeric simulation,the paper introduces the basic principle and experimental verification of the geotechnical centrifugal machine in the simulation blast and impact,illustrates some research,including the research on the ground blasting on the underground tunnels and other build-ings,and the simulation of the large-scale blast of the centrifugal machine,and points out the testing methods for the checkings of Three Gorge’s anti-detonating capacity.
