| 摘 要： | 通过全面的野外调查和历史资料统计分析,统计了枝柳线张家界工务段沿线的地质原生灾害、次生灾害和衍生灾害的数量,并研究了各种灾害的分布规律。针对既有线铁路的特征,选取了地质灾害的发育因子、基础因子和诱发因子作为评价指标,并且基于区域地质灾害评价预警的递进分析理论与方法（AMFP）,对原有方法进行了改进和拓展,形成了既有线铁路的地质灾害＂四度＂法评估方法。由此,分别计算了枝柳线张家界工务段地质灾害的发育度、潜势度、危险度和危害度（简称＂四度＂）,且据此进行了综合分区,为既有线铁路的地质灾害监测和管理提供科学依据。

| Abstract: | Through field investigations and historical data collection,the number and distribution of original geo-hazards,secondary geo-hazards,and derived geo-hazards along the Zhangjiajie district in Zhi-Liu railway were studied.Developmental factor,basic factor,and inducing factor were selected as index of existing railway geo-hazards evaluation analysis,with a corresponding method named four degree evaluating analysis method,which Was proposed by improving and developing the progressive analysis theory and method in regional geo-hazards evaluating and prewanning.The proposed method Was applied to evaluate the developmental degree,potential degree,dangerous degree,and harmfulness degree of geo-hazards along the Zhangjiajie district in Zhi-Liu railway.Geo-hazards zoning Was conducted according to the results of evaluation.What mentioned above could provide scientific basis for existing railway geo-hazards monitoring and governing. |
