摘要
针对煤田、矿山等巷道超前探水,隐伏陷落柱、构造裂隙等不良地质体探测的关键技术问题,应用有限元数值模拟技术实现了巷道三维复杂条件下激电观测的快速正演算法及程序。本文在三维有限元正演基础上,分析计算了巷道本身对巷道顶底板激电探测的影响规律,并用理论模型数据检验改正效果。
The rapid forward algorithm and program are carried out under 3 -D complex technological condi-tions with finite element digital analogy method aimed at key problems of tunnel advanced detection of water, bur-ied collapse pile and structure fissure, etc of bad geological bodies. In this paper, on the basis of 3 -D finite ele-ment forward algorithm, we have the analysis and calculation of influence rule of tunnel itself on IP survey of tun-nel roof and floor and detection, correction of the effect with the theoretical model data.
