为了查清岩溶塌陷引起松塘水库失水的原因与形成机理,在该地区进行了实地岩溶塌陷,地质环境,周边人类工程活动调查。本文通过资料分析研究,认为地质环境(特别是二叠系的地层岩性及构造特征)是引起岩溶塌陷的内在因素,库内取土筑坝和采矿抽排地下水人类工程活动则是引起岩溶塌陷的诱发因素。内在因素与诱发因素的形成均导致了水库漏水而失去蓄水能力。
In order to find out the causes and formation mechanism of water loss caused by karst collapse in Songtang Reservoir, the authors conducted a survey on the field karst collapse, geological environment and surrounding human engineering activities in the area. Based on the data analysis and research, this paper argues that the geological environment (especially the Permian stratigraphy lithology and tectonic features) is the intrinsic factor of karst collapse. The earthwork dam and mining drainage groundwater in the reservoir are the cause of karst collapse The predisposing factors. Internal factors and the formation of predisposing factors have led to the reservoir leakage and loss of water storage capacity.
