摘 要:收集了襄渝(襄阳—重庆)铁路南段2015—2017年的降雨量资料以及相关的地质条件资料。分别以万源—毛坝、宣汉—达州路段为研究对象,统计分析了降雨量因子与边坡溜坍发生次数的相关性。建立有效降雨量模型,取边坡溜坍发生前1周的降雨量计算有效降雨量,将有效降雨量作为雨量预警的关键性指标,分析其与边坡溜坍发生次数的关系。结果表明:万源—毛坝段以累积雨量作为雨量警戒值时的致灾降雨量为140 mm,以累积雨量+激发雨量作为雨量警戒值时的致灾降雨量为90 mm+22 mm;宣汉—达州段以累积雨量作为雨量警戒值时的致灾降雨量为150 mm,以累积雨量+激发雨量作为雨量警戒值时的致灾降雨量为90 mm+36 mm。The rainfall data and related geological conditions of the southern section of Xiangyang-Chongqing railway from 2015 to 2017 were collected and the correlation between various rainfall factors and occurrence times of slope surface slip was analyzed by taking W anyuan-M aoba and Xuanhan-Dazhou sections as research objects. An effective rainfall model was established,the effective rainfall value was calculated by obtaining the rainfall at one w eek before the occurrence of the slope surface slip,and the relationship between the effective rainfall and the occurrence times of the slope surface slip was analyzed by taking the effective rainfall as the key index to evaluate the rainfall early w arning. The results show the disaster-causing rainfall of Wanyuan-Maoba section is 140 mm when the cumulative rainfall is used as the warning value of rainfall and is 90 mm + 22 mm when the cumulative rainfall +stimulated rainfall is used as the warning value of rainfall,and the disaster-causing rainfall of Xuanhan-Dazhou section is 150 mm when the cumulative rainfall is used as the warning value of rainfall and is 90 mm +36 mm when the cumulative rainfall + stimulated rainfall is used as the warning value of rainfall.
