摘　　要：在了解泰莱盆地地形地质条件的基础上,根据高密度电阻率法对灰岩地区探测敏感的优点,采用高密度电法对泰莱盆地岩溶塌陷区进行探测,并结合该区地质概况和地球物理特征,对获得的视电阻率拟断面图高低阻曲线变化特征和反演图异常形态进行了分析,推断异常分布位置、范围、规模及产生的原因,得出地质解释。结果表明:应用高密度电阻率法可有效查明第四系覆盖层厚度和下伏基岩岩性,明确圈出岩溶的发育位置和断裂构造的位置,大致了解断裂构造在岩溶发育中的控制作用,为地质灾害调查工作提供一定参考依据。On the basis of understanding the topographic and geological conditions of the Tailai basin,based on the advantages of the high-density resistivity method for the detection of limestone areas,uses high-density electrical method to detect the Karst collapse area in the Tailai basin,and combines the geological profile of the area.According to the geophysical characteristics,the characteristics of the high and low resistance curves of the apparent resistivity of the apparent resistivity and the anomalous morphology of the inversion map were analyzed.The location,extent,scale and causes of the anomaly distribution were inferred,and the geological interpretation was obtained.The results show that the high-density resistivity method can effectively identify the thickness of the quaternary cover layer and the lithology of the underlying bedrock,and clearly define the development position of the karst and the location of the fault structure,and roughly understand the control of the fault structure in karst development.Role,provide a certain reference for geological disaster investigation work.
