高速公路隧道洞口浅埋段不良地质处治技术探讨

Treatment Technology Discussion on the Unfavorable Geology in Shallow Buried Section of Highway Tunnel Entrance

我国已经建成了较为完善的交通运输网络,但还会在施工过程中遇到多种问题。要提高高速公路的建设质量,保障其安:全性与稳定性,必须在作业中使用恰当的施工技术与加固技术。其中,土方刷坡、预注浆技术、预支护施工技术、锚网喷施工技术是施工团队在稳固和施工隧道洞口浅埋段时所使用的主要技术。

China has built a relatively perfect transportation network,but it will encounter many problems in the construction process.In order to improve the quality ofhighway construction and ensure its safety and stability,proper construction and reinforcement techniques must be used in the operation.Among them,the earth-brushing slope,pre-grouting technology,pre-protection construction and anchor net spraying construction are the main techniques used by the construction team in stabilizing and constructing the shallow buried section of the tunnel entrance.
