摘要
柳江水源地是奏皇岛市一个大型的地下水水源地,1987年6月正式投产供水。1988年3—8月出现280多个岩溶塌陷。并伴有不均匀地面沉降和地面裂缝,致使当地一些房屋出现诺开裂和变形,造成经济赔偿150万元。 本文是在塌陷区进行详细调查的基础上撰写的(?)着重对岩溶塌陷条件和塌陷动力因素进行了分析研究,并对塌陷的发展趋势和地面稳定性进行了探讨评价。最后提出了相应的防治对策。
Water source base of Liujiang is a large ground water source base. It is located in the karst area covered by Quaternary system. This water supply area had been in operation since 6 1987. Its average yield are 34000m3/d. Here 280 karst collapses occurred during Apr-Aug. 1988 Also non- uniform land subsidence and fissures occurred. It maked buildings fractured and deformed
This paper deals with the conditions and dynamic factors of karst collapses. The developing trend and the stability of land surface are discussed. Finally, preventing measures are suggested.
