目前常用的电阻率测深方法中,有多种不同排列装置形式的方法,但它们一般只适宜于解决水平层状地层的有关地质任务。为了解决非层状地质体(溶洞、有限大小的金属矿体等)的探测,我们近年来共同试验研究了五极纵轴直流电测深法。这种方法在一定的地电条件下,它对于非层状地质体有较好的勘探效果。从一九七四年起柳州铁路局勘测设计所首先在石灰岩岩溶地区供水水文地质勘探中试验此种方法,成都地质学院进行了该方法的理论研究,并进行了大量的正演计算和室内模拟试验工作;理论计算、模拟试验和野外勘探实例对比说明。与目前广泛应用的各种电阻率测深法相比较,纵轴直流
There are many different ways of arranging devices in the current resistivity sounding methods, but they are generally only suitable for solving the related geological tasks in horizontal stratigraphic formations. In order to solve the non-layered geological body (cave, limited size of the metal ore body, etc.) detection, we have in recent years jointly studied the five-pole vertical axis DC sounding method. This method under some geoelectric conditions, it is non-layered geological body has better exploration results. Since 1974, the Survey and Design Institute of Liuzhou Railway Bureau first tested this method in hydrogeological exploration of water supply in limestone karst areas. The Chengdu Institute of Geology conducted a theoretical study of the method and conducted a large number of forward calculation and in-house simulation Experimental work; theoretical calculations, simulation experiments and field exploration example contrast instructions. Compared with the widely used resistivity soundings, the vertical axis of direct current
