摘要
文章以重庆市轨道交通三号线一期工程华新街-观音桥区间隧道爆破开挖工程为例,从爆破振动效应的产生及其影响因素的理论分析入手,结合工程实践中爆破振动效应实际测试结果,对隧道爆破减震问题进行系统的综合研究,得出一系列相应的隧道爆破施工减震技术措施。
With the tunnel blasting excavation engineering between Huaxin Street-Guanyinqiao in Phase I engineering of Chongqing Rail Transit Line 3 as the example,this article started from the theoretical analysis on the generation of blasting vibration effect and its influencing factors,and in combination with actual test results of blasting vibration effects in engineering practice, it systematically and comprehensively studied the tunnel blasting damping problem, and obtained a series of corresponding tunnel blasting damping technok）gy measures.
