| 摘 要： | 结合在建的兰渝铁路木寨岭隧道炭质板岩段实际情况，寻找解决控制高地应力大变形的方法，通过在木寨岭隧道7#斜井进行超前大钻孔、超前导洞应力控制方法的现场试验，根据与原施工段监控量测结果进行对比，二者虽对变形的控制起到一定作用，但就其可行性而言，还需继续研究和完善。

| Abstract: | Muzhailing tunnel on Lanzhou-Chongqing railway passes through carbonaceous slate ground,where large deformation occurs.In order to establish the methods to control the large deformation,advance large-diameter boreholes and pilot heading are installed in No.7 inclined shaft of Muzhailing tunnel so as to perform stress control tests.Comparison is made between the monitoring data in the test section and those in the original section.The test indicates that advance large-diameter boreholes and pilot heading are... |
