深基坑爆破地震危害控制研究
|
摘要
介绍了爆破地震波作用下既有建(构)筑物振动破坏机理,探讨了避免爆破地震对既有设施造成危害的措施和方法,通过对某地铁基坑工程爆破危害性的分析计算,采取相应的措施予以保护,避免了爆破对基坑带来的安全风险。
The paper introduces the existing building vibration damage mechanism under blast earthquake action,and explores measures and methods of avoiding blasting earthquake damaging existing facilities.Through analyzing and calculating blasting hazard of the subway foundation engineering,it adopts corresponding measures,and avoids blasting risk upon foundation security.
