摘要
本文主要研究了铁路岩溶塌陷灾害发育的物质基础和基本规律 ,给出了根据线路地表地质地貌以及其它情况判定岩溶塌陷危险性的单因子迭加判定方法 ,该方法在南昆铁路判定结果和现场钻控结果基本相符 ,具有一定实用价值。
The material foundation and basic law of karst collapse's evolution are treated in the paper.Based on previous scholars'work,a method predicating railway's karst collapse by plus single evaluating factor together is developed.The evaluating factors are selected from those that can be observde easily along a railway,such as geological structure,landforms,etc.In the Nan Kun Railway,the dangerous distribution of karst collapse predicated with the method conforms to the result of drilling well,showing that it can be used practically.
