| 摘 要： | 井间电阻率层析成象是一种探测地下浅部精细结构的物探方法，它主要用于解决工程地质问题。本文采用２．５－Ｄ有限元法，针对井间电阻率层析成象中的ＡＭ观测系统进行了反演成象计算。文中首先计算了灵敏度矩阵，然后给出了一种电阻率层析成象反演算法—平滑度约束反演，理论模型的计算和实际资料的处理，都证明了该算法的有效性

| Abstract: | Crosshole resistivity tomography is a kind of high accurate geophysical prospecting technique. It is mainly used for prospecting the shallow structures and enginerring geophysics. In this paper, sensitivity matrix is calculated and an inverse imaging algorithm, that is, smoothness constrained inversion is presented. In order to examine the effectiveness of the algorithm, two synthetic experiments and a particular real example are performed. The results show that the algorithm is stable and convergent. |
