摘　　要：随着工程勘察、文物保护、地质灾害治理等工作需要详细了解地下地质体形态以及构造,越来越多的物探方法被用于灾害治理、工程设计等工作中,成为了解地质情况,前期勘察必不可少的手段。本文以高密度电法为例,通过对采集的数据进行解释推断,分析该方法在寻找地下空洞的空间位置和展布形态上的应用效果。此项成果,对今后在类似地区开展地下空洞区域探查提供了参考,具有一定的借鉴意义。With the need for detailed understanding of the morphology and structure of underground geological bodies in engineering survey,cultural relics protection,geological disaster management,etc.,more and more geophysical prospecting methods are used in disaster management and engineering design,which have become an indispensable means to understand the geological situation in the early stage.In this paper,taking the high-altitude electric method as an example,the application effect of the method in finding the spatial location and distribution morphology of underground cavities is analyzed by interpreting and inferring the collected data.This achievement provides a reference for the exploration of underground cavity areas in similar areas in the future,and has certain reference significance.
