高速公路隧道掘进爆破施工技术研究

Study on Blasting Construction Technology of Expressway Tunnel Driving

为解决高速公路隧道爆破掘进问题,结合某高速公路隧道工程实际情况,对其与既有线净距较小情况下的爆破掘进施工技术进行分析,提出相应的技术要点,以期为相关人员提供参考。

In order to solve the problem of blasting tunneling of expressway tunnel,this paper analyzes the blasting tunneling construction technology under the condition that the net distance between the expressway tunnel and the existing line is small,and puts forward the corresponding technical points,in order to provide reference for relevant personnel.
