摘　　要：为解决直流电法中三维地电体静电场的计算问题,通过静电类比,把稳定电流场的计算换为相应的静电场计算,再利用模拟电荷法求解。采用模拟电荷法建立了可以模拟稳定电流场的方程组,利用点电荷作为模拟电荷解决了三维地电体静电场数值模拟问题,编制了模拟计算程序。对球体这一典型的地电模型进行了模拟,结果与理论值相比较理想。该算法解决了以往求解静电场算法复杂、剖分困难等问题,可为电法勘探的正反演理论研究提供依据。In order to solve the static electric field numerical calculation problem of three dimensions underground object in electrical prospecting, we change stable electric current field calculation into static electric field calculation by using static electric analogy, then calculate the static electric field by simulate charge method. In this article we build the equation which can simulate stable electric current field by simulate charge method, and solve the static electric field numerical calculation problem of three dimensions underground object by using point charge as simulator charger. We also write the program, the calculation result is satisfaction. It can provide important basis for straightforward and back forward theory research of electrical prospecting.
