| 摘 要： | 南水北调调西线工程线路地层倾角陡、沟谷纵横、地质构造复杂、隧道长,埋深大,同时要对1000 m以内的构造、岩溶、岩层划分等进行地质超前预报,利用以往的超前预报方法无法满足工程施工的要求.对于深长埋隧道断层的施工地质超前预报,本文使用CSAMT法探测技术,并进行了近场校正、各向异性校正、静态校正、分辨能力校正和联合反演等手段,进行了实际探测和对比分析,并取得了较好的探测效果.

| Abstract: | The south-north water transfer west route project has obvious characteristic.It is stratum slope angle cliffy,channel and vale excessively,geological structure complexity,tunnel long and deeply buried.In the mean time it must advance forecast to find out the geological structure,fault,and rock dissolve cavity and stratum transformation in the 1000 meter.It can not forecast and reach project construct according to the anciently method.This paper introduces the CSAMT technology to detect deeply buried tunnel fault and advance geological forecast in the south-north water transfer west route project.Meanwhile it research the near area revise,anisotropy revise,static state revise and resolving power revise,and use the method of unite reverse calculate etc.It carries through contrast and analysis with the actual inspect sample and obtain approvingly result. |
