高密度电法在泰安羊娄—旧县岩溶塌陷探测中的应用

High-density electrical method used in the application of karst collapse

泰安东南羊娄—旧县是典型的岩溶塌陷的受灾区域,前人在此区内进行了多次研究并得出了该区域内地质推断。为验证这些推断,本文在总结前人研究的基础上,利用高密度电阻率法对该区近几年塌陷是否仍然进行以及目前发育的最新程度进行了对比总结。此次基本验证了前人在工作区内关于塌陷是由于地下水水位变动的基本论断,总结了开展对比性物探方法的可行性,最后发现本区内地下水的开采问题仍然没有规划好,地下水水位依然在上下波动之中,特别是遇上丰水期或者枯水期的交界时候塌陷发生的可能性非常大。

Southeast Taian,Yang Lou-Jiuxian is a typical karst collapse of the affected area.The previous number in this study area were obtained in the region of geological inference.To verify these inferences,this paper,based on previous studies,still using high density resistivity method subsidence in the area find the collapse is still ongoing and the current level of development are compared with the latest summary.The basic authentication of the previous collapse in the work area on the groundwater level changes due to the basic thesis,summarizes the comparison of geophysical methods to carry out the feasibility of,and eventually found the exploitation of groundwater in this region the problem still unplanned,the groundwater level is still fluctuating up and down,the collapse occurred especially in case of wet season or dry season.
