为确保地铁隧道爆破施工时邻近地表建筑物的安全,需分析隧道爆破振动影响因素的主次关系,从而优化爆破方案,制定相应的减震措施。以珠江三角洲城际快速轨道交通广州至佛山段工程为依托,采用灰色关联分析方法对地铁隧道爆破振动的影响因素进行分析。结果表明:珠江三角洲城际快速轨道交通矿山法段爆破振动影响因素的主次关系依次是最大起爆药量、爆心距、高程差、水平距离。

In order to ensure the safe use of adjacent surface buildings during blasting construction of subway tunnels, it is necessary to analyze the primary and secondary relationship of the influencing factors of tunnel blasting vibration, so as to optimize the blasting scheme and formulate corresponding damping measures. Based on the project of Guangzhou to Foshan section of Intercity Rapid Rail transit in the Pearl River delta, influence factors of blasting vibration of subway tunnel are analyzed by using grey correlation analysis meth- od. The results show that the primary and secondary relation o...
