滇西地区炭质页岩隧道变形整治

国内炭质页岩变形隧道并不少见，但是滇西地区炭质页岩变形隧道尚属首例，松桂1号隧道位于青藏、滇缅、印尼巨型”歹”字型体系东支中段与三江经向构造体系符合部位。因特定的大地构造环境，特殊的区域地球动力学条件和强烈的现代地壳运动，导致新构造运动十分强烈，主要表现为高原隆起、活动构造、地热显示、地震、褶皱、断层等。通过对围岩地质构造与隧道稳定性的分析和此类围岩实际开挖的研究与探讨，以及结构加强适应性研究及施工方案选择，总结一套安全、快速通过此地层的应对方案及措施，积累了施工经验，为今后类似工程施工提供了科学依据。

Deformation Treatment for Charcoal Shale Tunnels in the West Yunnan Province

In our country, the deformation tunnel through the charcoal shale is common; however, tunneling in the charcoal shale in the west Yunnan Province is the first experience. No. 1 Songgui tunnel is located in the overlapping area of the middle section of the east branch of the large 歹-shape system of Qinghai Province, Xizang Province, Yunnan Province, Burma and Indonesia and the Sanjiang structural system. In this area appear the tableland raising, moving structure, geothermal energy, earthquake, fold and fault, because of the special geotectology structure environment, particular area geodynamics conditions and intense modem earth movement with the result of strong new structural movement. In this article, after analyzing the geological structure of adjoining rocks and the tunnel stability, studying and researching the actual excavation of the adjoining rocks and discussing the compatibility of structure strengthening, a safe and rapid solution schedule and measures tunneling in this kind of stratum has been summarized to provide the constructional experience and scientific basis for the similar works.
