鄂州市泽林村岩溶塌陷反复变形成因机制分析

Genetic Mechanism Analysis of Repeated Deformation of Karst Collapse in Zelin Village,Ezhou City

鄂州市泽林村为隐伏岩溶分布区。自2011年以来,多次出现岩溶塌陷变形,直接威胁周边居民生命财产安全、武九铁路正常运行以及泽林镇建设发展,潜在经济损失巨大。通过收集资料,结合勘查手段,以武九铁路K84+370段下行线路基东侧塌陷为例,研究该区岩溶地面塌陷产生的地质环境、形成条件、发育规律和影响因素;在此基础上,分析该区反复变形的成因机制,对指导该地区地面塌陷后续防治工作提供技术依据。

Zelin village in Ezhou City is a hidden karst area.Since 2011,many karst collapse deformation,a direct threat to the lives and property of the surrounding residents,the normal operation of the Wuhan-Jiujiang railway and the development of Zelin town,the potential economic losses are huge.In this paper,the geological environment,forming conditions,developing rules and influencing factors of karst ground collapse in the area are studied by collecting data and combining exploration means,taking the collapse of the east side of the foundation of the K84+370 section of the Wuhan-Jiujiang railway as an example,the mechanism of repeated deformation is analyzed to provide technical basis for the follow-up prevention and control of ground subsidence in this area.
