Susceptibility analysis on influencing factors of rockfalls and landslides in Tibet

  • 摘要: 西藏地区地形地貌复杂,构造活动强烈,气候条件多样,地质灾害频发,对全区经济建设和社会发展的影响日趋显著。其中,崩塌、滑坡是西藏地区常见的地质灾害,为了定量分析研究区内崩塌、滑坡影响因子的敏感性,文中基于GIS与确定性系数分析方法,选取了坡度、坡向、地形起伏度、坡形、高程、距地质构造距离、河网密度、工程地质岩组等8个因子开展了崩塌、滑坡影响因子敏感性分析。分析结果表明:(1)西藏地区崩塌、滑坡影响因子高敏感性区间为:斜坡坡度大于30°,坡向为南东向、南向、南西向,地形起伏度在200~800 m/km2,坡形为凹形坡,高程在1 500~4 500 m,距地质构造距离0~3 km,河网密度>0.5 km/km2,代号为YJ2、TS1、TS2、BZ1的岩组,灾害与影响因子之间表现出较好的相关性。(2)影响因子间的敏感性大小:坡度>工程地质岩组>高程>坡形>河网密度>地形起伏度>坡向>距地质构造距离。研究结果对西藏地区崩塌、滑坡易发性评价工作提供了参考。
