摘要
在浅埋、软岩条件下用钻爆法开挖隧道,安全顺利下穿城市道路需要解决诸多的技术问题,并且做好施工监控。结合工程实际探讨了施工开挖和微震爆破理论、超前导管注浆支护、量测监控技术等施工控制技术,对工程实践有着重要的指导意义。
When there is made the excavation and incompetent rock, safely and smoothly cutting of tunnel by drill - blasting through do well construction monitoring. In the light of practical method under shallow embedding urban road needs to settle multiple technical issues and project, the paper makes an approach to the theories about excavation construction and micro - vibration blasting, as well as the construction controlling techniques such as the leading tremie concrete supporting arid the measurement monitoring etc,which possess an important instructing significance to simular project.
