摘要 广西某铁路站位于岩溶强发育区,近年来,该铁路沿线中间及两侧频频产生岩溶塌陷,对铁路的安全运行造成巨大的影响。文章基于广西某铁路站岩溶塌陷整治工程调查综合分析,对该铁路沿线岩溶塌陷的影响因素进行归纳总结,初步阐明了岩溶塌陷孕育机理,为铁路岩溶补强提供地质依据。 A railway station in Guangxi is located in highly developed karst area.In recent years,karst collapse frequently occurred around the middle and both sides of the railway,which has a great impact on safe operation of the railway.Based on comprehensive analysis of the karst collapse remediation project,the factors that impact the collapse along the railway are summarized,and preliminarily clarifies the development mechanism of the karst collapse,providing geological basis for karst reinforcement along the railway.
