摘要
根据勘探和地面塌陷资料,本文分析了蔡家关岩溶塌陷的形成条件,包括岩溶发育特征,第四系岩性结构和厚度,岩溶水文地质条件及引用地表水期间岩溶塌陷的发展趋势,研究了岩溶塌陷的发育与分布规律。为预防地面塌陷,为建筑物基础的防塌结构设计,及可能塌陷区建筑物基础形式的确定等提供地质依据。
On the baisi of the materials on the geological prospection and ground callapse, the formation conditions of ground callapse including features of the Karst development and the lithology structure and thickness of the Quaternary system as well as the Karst geohydrology geology condition and the development of Karst collapse during the utilization of surface water in Caijiaguan are analysed in this paper. The development and distribution rules of ground callapse are also discussed and studied. Geology reference is provided for the design of protection and for the choice of the rigion from karst collapse, the type of foundation of structures in the area where ground collapse may take place.
