摘要
隧洞施工中,由于洞口地质条件各异,成洞所采取的工程措施有很大差别。能否安全、快速成洞是隧洞工程施工的关键。本文介绍了东北某大型输水隧洞工程几种典型地质条件下洞口段的成洞方式,并进行了比较评价,以期对今后的隧洞施工有所借鉴。
During the construction of the tunnel,the means used in tunneling is difference with the difference of the geology condition.The safe and quick tunneling is the key of the construction.This paper introduces the tunneling methods of the structural opening of the large-scale water delivery tunnel located in the northeast under several typical geology conditions,and compares and evaluates them,which can provide the reference for other resemble projects.
