摘要
地质灾害的发生受多种因素影响 ,通过主成份分析和判别分析建立多因素影响地质灾害预测数学模型 ,并应用于铁路沿线岩溶塌陷的预测评价 .结果表明 。
Sinkhole of karst prediction is difficult due to many influence factors. In this article, based on the basis of main-factor-analyses and distance-estimation, a mathematics model for sinkhole of karst along railway is set up. Tts application on the sinkhole along railway shows this model is reasonable.
