摘　　要：工程建设中,防空洞、落水洞、溶洞等空洞的存在会对建筑物及构筑物地基等地下工程产生不利影响。文章运用有限元差分法的正演和最小二乘法反演软件,对单层不同深度的空洞进行模拟,得出空洞的正反演模型。通过山西某地的高密度电法探测防空洞工程实例的反演试验,验证了高密度电法在不同深度数值模拟的规律性。In engineering construction,the existence of air-raid shelters,sinkholes,karst caves and other voids will have adverse effects on underground engineering such as the foundation of buildings and structures.In this paper,the forward and inverse models of single layer voids with different depths are obtained by using the forward modeling and least square inversion software of finite element difference method.Through the inversion test of a high density electrical method detecting air-raid shelter project in Shanxi Province,the regularity of numerical simulation of high density electrical method in different depths is verified.
