| 摘 要： | 随着公路建设规模日益扩大,3车道、4车道的超大断面公路隧道越来越多。隧道浅埋段覆盖层薄、围岩稳定性差,开挖时易出现坍塌等工程事故,是超大断面隧道施工技术的重点和难点。结合深圳盐排高速公路盐田隧道的施工实践,介绍浅埋段施工的一些经验和技术体会,可为类似工程施工提供参考。

| Abstract: | Along with highway development three or four-lane in the highway of supebig cross section tunnel has grown up more and more.Shallow-buried segment of tunnel overburden layer is thin and adjoining rock stability is bad,While cutting,the collapse is the difficult point of super big cross section highway of tunnel construction technique.Based on the construction practice of Yantian tunnel in Shenzhen-Yanpai highway,it introduces the experiences and technique of shallow-buried segment constructioning,which will provide the reference for similar engineering construction. |
