【摘要】：拟建西安至延安高速铁路位于黄土高原,由于河流冲刷、人类工程活动等因素,其沿线发育大量黄土滑坡,具有密度大、易滑动、难防治等特点,严重威胁铁路行车安全。在陕西I49E007004(耀县)幅1∶5万环境地质调查项目研究报告的基础上,结合遥感解译成果,对沿线的滑坡灾害发育特征及防治对策进行分析。分析认为:西延铁路沿线的黄土滑坡可归纳为3类,分为黄土内滑坡、黄土-基岩接触面滑坡、黄土-泥岩滑坡,且其分布的空间特征具有不均匀性、群集性和延续性,并因地制宜,对线路沿线的黄土滑坡提出防治对策,为拟建西延高铁沿线黄土滑坡灾害的防治提供相关参考和依据,同时助力黄土高原滑坡灾害的防治。
[Abstract]:The proposed high-speed railway from Xi'an to Yan'an is located on the Loess Plateau. Due to the factors of river erosion and human engineering activities, a large number of loess landslides are developed along the route, which have the characteristics of high density, easy sliding and difficult to prevent and cure, which seriously threaten the safety of railway operation. Based on the research report of the 1: 50 000 environmental geological survey project in the I49E007004 range of Shaanxi Province, and combining with the interpretation results of remote sensing, the development characteristics of landslide disaster along the route and the prevention and control measures are analyzed. The analysis shows that the loess landslide along the west extension railway can be classified into three categories, which are the loess internal landslide, the loess-bedrock interface landslide, the loess-mudstone landslide, and the spatial characteristics of their distribution are non-uniform, clustered and continuous. According to the local conditions, the countermeasures are put forward to prevent and cure the loess landslide along the railway line, which provides the relevant reference and basis for the prevention and control of the loess landslide along the railway line in the West Yancheng, and at the same time helps to prevent and cure the landslide disaster in the Loess Plateau.
