炭质片岩地质隧道施工变形控制

Deformation control for tunnel construction with carbonaceous shale geology

针对长大隧道施工安全风险高、地质复杂、工期紧、质量要求高的特点,通过分析襄渝二线新蜀河隧道炭质片岩地质特征,对隧道变形控制施工技术做了简要介绍,同时提出了相应的技术措施及施工建议,最后证实了正台阶法的合理性。

In light of features of ultra-long tunnel construction, such as high security risk, complex geology, short construction period, and high quality requirements, through analyzing carbonaceous shale geological features of Xiang-Yu line two Shuhe tunnel, it briefly describes tunnel deformation control technology, and puts forward corresponding technical measures and construction suggestion. In the end, it proves the rationality of positive benching tunneling method.
