摘要
深长埋隧洞隐伏断层问题是关系到隧洞(道)选线以及将来施工的关键技术问题,常规的地质勘察最有效的手段是地面地质测绘、钻探、洞探和物探等,但由于埋深大、洞线长、穿越的地质单元复杂多变,技术难度大,国内外探测成功的工程实例不多,结合南水北调工程实例,探讨了CSAMT法在探测深埋长隧洞中隐伏断层的应用技术,提出了近场问题和静态问题的校正方法。
The detecting Buried fault of the deeply Buried tunnels is the important technology question in the select tunnel line and construct tunnel. Geologic survey, drilling and geophysics is the best of detect means in the last time. It has obviously characteristic that tunnel is deeply Burled faults, longer line tunnel, complexity and levity geologic condition and difficultly detect technology etc. so that it has a little success detect sample in the china or in the other country. This paper discuss the application technology of CSAMT to detect deeply Buried tunnels faults, based on the project of South-to-North Water Transfer. Meanwhile it brings forward the revise method of near filed question and static question.
