摘要
该文以青草沙五号沟泵站基坑内支撑爆破拆除施工为背景,通过数值模拟分析研究了各项爆破参数对基坑内部结构受到的爆炸应力影响,并通过振动荷载的动力响应分析,从而为判断爆破振动是否会造成内部结构产生微观损伤提供了一种方法。
According to the foundation pit brace blasting demolition construction of Qingcaosha Wuhaogou Pumping Station,the article analyzes and studies the influence of various blasting parameters on the blasting stress for the inner structure of foundation pit by the numerical simulation.The dynamic response analysis of vibrating load provides a method to verdict whether or not the blasting vibration will cause the microscopic damage of inner structure.
