采用高密度电阻率测量系统进行现场电阻率探测，根据 AGI 探测数据并结合工程地质及水文地质特征分析高阻区域与低阻区域的性质，得出以下结论：①高阻体主要是由于溶洞、溶隙以及岩土体坍塌引起，高阻体主要分布于大理岩地层中；②低阻体中一部分是大理岩地层中的溶洞与地表水导通，使得溶洞充水引起，另一部分是由位于马架山和灵山组富含水地层中的岩溶水和溶隙水所致。通过分析，可以了解溶洞空区与溶洞充水区的空间分布情况，并指出它们之间的相对独立关系的及各自形成塌陷和突水等地质灾害的条件。实地探测结果可为进一步深入研究复杂空区的稳定性提供可靠依据，对于进行矿区开采引起地表稳定性分析亦具有一定的参考价值。

The high density resistivity measurement system is used to conduct filed resistivity detec-tion,according to the AGI detection data and engineering geological and hydrogeological characteristics, the nature of high resistance area and low resistance area are analyzed.The analysis results show that:①the high resistance body is caused by karst cave,dissolve gap and collapse of rock and soil mass,and it is mainly distributes in the marble formation;②part of the low resistance body is caused by karst water fill-ing caused by marble karst cave and surface water in the stratum conduction,the other part of the low re-sistance body is caused by the karst water and solution crack water located in the water bearing ground of trestle mountain and Lingshan group formation.By above analysis,the spatial distribution of the cave empty area and the water filling area of karst cave is understood,the relatively independent relationship of the cave empty area and the water filling area of karst cave is pointed out,besides that,the formation con-ditions of geological disaster and water bursting are also specified.The field detection results can provide reliable basis for further researching on the stability of the complex empty,it also has certain reference value for analyzing the stability of mining surface.
