摘要
本文围绕徐州城市轨道交通2号线06标段中淮区间隧道竖井爆破工程,通过系统深入地开展竖井控制爆破施工技术的研究工作,并优化竖井爆破施工技术方案,通过中心区域预处理措施增加自由面,减少岩石夹制作用,总结出了竖井爆破施工中安全高效的控制措施。
In this paper,based on the shaft blasting project of Zhonghuai tunnel in the bid section 06 of Xuzhou Urban Rail Transit Line 2,through the systematic and in-depth study of the shaft controlled blasting construction technology,and optimization of the shaft blasting construction technology scheme,through the central area pretreatment measures to increase the free surface,reduce the role of rock clamping,summed up the safe and efficient control measures in the shaft blasting construction.
