【摘要】 拉林铁路处于软岩极为发育、海拔最高、构造活动最为强烈的地区,发育大量的地质灾害,严重威胁铁路的选线与施工。本文在收集相关资料和大量野外调查的基础上,分析影响因素,总结研究区内地质灾害发育特征与分布规律,建立相应的评价体系,运用定性与定量结合的评价方法进行地质灾害危险性评价与分区。研究结果表明:运用定性与定量相结合的分析方法,综合考虑研究区地质灾害发育特征、灾害分布规律、工程活动等因素进行地质灾害危险性评价,将整个区域分为3个区,其中轻度危险区占研究区45.3%,中度危险区占33.5%,重度危险区占21.2%。本文完整地论述了拉林铁路沿线崩滑地质灾害性评价的技术路线,划分出沿线不同区域的危险性,对于保证拉林铁路工程建设的顺利进行具有重要意义。更多还原

【Abstract】 Lalin railway located in the area where soft rock extremely developed,altitude is highest,and structural movement most intense.In which area,developed a large number of geological disasters that seriously threat the line selection and construction of the railway.Therefore,this paper based on the relevant data collection and field investigation,analyzed the influence factors,summarized the development characteristics and distribution regularities of geological disasters in the study area,established a relevant evaluation system,utilized qualitative evaluation methods to assess and regionalize the risk of geological disasters.The results show that:utilizing the qualitative analysis methods,comprehensive considerate the development characteristics and distribution regularities of geological disasters,engineering activities and other factors to assess the risk of geological disasters,divided the study area into three districts,in which,light danger district accounted for 45.3%of study area,moderate danger district accounted for 33.5%,catastrophic danger district accounted for 21.2%.This paper completely discussed the technic technical route of falling and landslide geological disasters assessment along the Lalin railway,categorized the risk of different area along the railway,it has an important significance to guarantee the smooth progress of Lalin railway construction.更多还原
