徐州市区地面塌陷分布规律及诱发机制研究

A CONTACT STUDY ON DISTRIBUTION AND ORIGIN OF THE GROUND COLLAPSE IN URBAN AREA OF XUZHOU

徐州市区地面塌陷开始于20世纪80年代中期,诱发地面塌陷的主要因素为岩溶水地下水的长期不合理开采。本文在概述水文地质条件、开采利用及动态变化情况的基础上,通过对塌陷点空间分布规律分析,较系统地研究了地面塌陷形成的诱发机制,并提出了防治对策。

Surface collapse started in the mid-1980s in urban area of Xuzhou, Risk factor of surface collapse is permanent and unreasonable exploitation of Karst water, on the basis of introduces hydrogeology conditions, the cases of Karst groundwater exploitation and Karst groundwater leve dynamic change, through analysis the spatial distribution of the collapse point. This paper study systematically forming mechanism and risk factor of surface collapse . At last, the author proposes prevention measure of surface collapse.
