摘要
通过电流分布特征的研究,给出了覆盖层厚度确定的方法.利用数值模拟计算进行了误差分析,给出了不同地电断面情况下的误差方向.与常规的电测深法相比,本法要求的野外工作量小,解释方法简单,精度较高.
Based upon a study on the current distribution characteristics, a method for determining thicknessof the overburden over a relief bedrock was developed. An error analysis has been made by using numeiical simulation and an error distribution direction for different geoelectric sections could be obtained.In comparison with conventional apparent resistivity sounding methods, our method is simple in interpretation technique and high in precison. In addition, only a small amount of field work is required.
