摘要
高密度电法是以地下各类地质体电性差异为基础,通过人工场源建立地下稳定的电场,并研究场分布规律来解决各种地质问题。本文主要通过高密度电法原理,以正演模拟为基础,研究了高密度电法在水域卵石区进行工程勘察的可行性,同时介绍了其在西气东输管线探测中的应用实例。实践证明:高密度电法在水域卵石区勘察基岩面深度及起伏形态方面效果较好。
The principle of Multi-electrode Electric Method（MEM） is based on the electrical difference of geological structure underground,establishing a stable artificial electric field and studying its distribution,MEM can figure out many kinds of geological problems.The paper mainly describes the principle of Multi-electrode Electric Method（MEM）,based on forward modeling,demonstrating the feasibility of engineering investigations in the regions of cobble stone,and the paper also introduces the application of MEM in the pipeline detection of project of natural gas transmission from West to East China.It proved that MEM has a good effect in the detection of depth and fluctuation of bedrock interface in the region of cobble stone.
