摘要
以海客道隧道工程为例,介绍了超前大管棚预支护技术在浅埋大跨径隧道中的应用,总结了大管棚在通过浅埋破碎围岩带时的作用,实践证明大跨径隧道洞口的软弱破碎围岩地段采用长大管棚施工工艺,具有显著的经济效益和社会效益。
Taking the Haikedao tunnel construction as the example, the thesis introduces the application of leading steel pipeline shed previous timbering technology in the shallow large-span tunnel, sums up the influence of leading steel pipeline through the shallow crushed surrounding rock lane. Practice proves that the application of leading steel pipeline construction technology on the soft crushed surrounding rock lane at the entrance of the large-span tunnel has remarkable economic and social benefits.
