摘　　要：为快速准确查明岩溶塌陷、滑坡、崩塌堆积等复杂地质条件下地质灾害的空间分布特征,在该类地质区,采用伪三维和真三维高密度探测技术,对其探测方式、反演模型、解释效果等方面进行了对比分析研究。结果显示,伪三维可以较清晰呈现出溶洞的现场位置及空间分布特征,真三维对地下围岩层位反馈较好,二者都与钻孔资料吻合较好。In order to quickly and accurately identify the spatial distribution characteristics of geological disasters under complex geological conditions, such as karst collapse, landslide and collapse accumulation,the ＂ pseudo-three-dimensional ＂ and true three-dimensional high density detection technology are used in this kind of geological area,through the analysis and comparison of the detection mode,the inversion model, and the interpretation effect. The results show that ＂ pseudo-three-dimensional＂ can clearly show the location and spatial characteristics of the karst cave,and the true three-dimensional feedback of the underground rock layer is better,and the two are in good agreement with the borehole data.
