The study of geological forecast to deeply buried tunnel fault in south-north water transfer west route project

DENG Hong-liang1, XIE Xiang-wen1,2,GUO Yu-song1,2(1.Beijing University of Technology,Beiijng 100022,China;2.Institute of Geophysical Prospecting,YREC,Zhengzhou 450000,China)  
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.
