摘要
通过高频大地电磁测深法在青海某山区三叠系地层内寻找岩溶裂隙水的应用,结合工作区内的地层电性特征,分析了不同电阻率对应的不同地层岩性及溶隙、裂隙发育及富水性情况,从反演剖面上分析岩溶裂隙水的分布范围,总结高频大地电磁测深法在三叠系地层中找岩溶裂隙水的应用效果,经过钻孔验证,高频大地电磁测深法在三叠系地层中找岩溶裂隙水是可行的。
In this paper,we have made a research of the high frequency magnetotelluric sounding method in a certain mountain area of Qinghai Triassic strata for the application of karst fissure water according to the stratigraphic electrical characteristics of the workspace.We have also made the inversion profile analysis of the distribution of karst fissure water,corresponding to different resistivity of different lithologic characters and dissolve gap,including the fracture and hydrogeology condition.It sums up the high frequency magnetotelluric sounding in the Triassic strata for the application effect of karst fissure water proven by drilling.And high frequency magnetotelluric sounding find karst fissure water in Triassic strata is feasible,we think.
