隧道穿越水库下断层破碎带帷幕注浆施工技术

Tunnel Passing through Fault Broken Zone in Reservoir Curtain Grouting Construction Technology

通过燕居岭隧道穿越水库下断层破碎带施工实例,系统地介绍了采用帷幕注浆加固围岩的原理、设计、施工方法、施工工艺、浆液调制等,对隧道穿越水库下断层破碎带提出了一种行之有效的施工方法,该方法对同类工程具有借鉴作用。

Based on the example of Yah Juling Tunnel passing through under the reservoir fault fracture zone, the paper systematically introduces the curtain grouting reinforcement of surrounding rock, design principle, construction method, construction technology, slurry modulation of tunnel passing through under reservoir, fault fracture zone presents an effec-tive construction method, this method has reference to similar projects.
