本文用有限单元法对坑道内的直流电阻率测深进行数值模拟计算。

In this paper, we performed modelling of DC resistivity sounding in tunnel using the finite element method (FEM).

先从理论上作了分析，然后利用ANSYS软件进行了直流电阻率剖面和电阻率测深法的模拟计算。

Then simulating calculation of profiles and soundings of the DC electro-exploring method are numerically carried out, supported by ANSYS that is a software based on the finite element analysis method.
