摘要
川藏铁路是自然、地质环境最为复杂的铁路工程,山地灾害作为局部乃至全线的关键控制节点,关乎川藏铁路建设的成败。川薇铁路康定—昌都段全长近700km,地貌类型多样,地质条件复杂,崩塌滑坡等山地灾害极为发育。通过详细的野外调查,并结合遥感解译等方法,查明了康定至昌都段铁路沿线共发育滑坡206处,崩塌186处,其中大型、特大型滑坡崩塌灾害80处,对铁路工程存在潜在危害或影响的滑坡66处,崩塌40处。在此基础上,将对铁路工程有影响的典型滑坡分为降雨型滑坡、地震型滑坡、构造和坡脚侵蚀综合作用型滑坡、冻融型滑坡和工程型滑坡,典型崩塌分为硬岩类崩塌和软岩类崩塌,并对不同类型典型滑坡和崩塌(如白玉县德沙滑坡、江达县古齿乡滑坡、理塘县毛亚坝滑坡、巴塘县措普沟崩塌)的特征、成灾机理及其对拟建铁路的危害和影响等进行了深入分析。
Sichuan-Tibet railway is a railway engineering with the most complicated natural and geological conditions.Mountain hazards,as key controlling points of local or whole railway line,affect the success or failure of the Sichuan-Tibet railway construction.The Kangding-Changdu section proposed Sichuan-Tibet railway has nearly 700 km long.The section has complex geoloigical conditions and various landforms.By field survey and remote sensing interpretation,we find out that there are 186 collapses and 206 landslides,and 66 landslides and 40 collapses have a potential hazard and influence on the proposed railway engineering in the section.On this basis,we firstly classify the landslides affecting the railway engineering into 5categories.They are respectively rainfall-induced landslides,earthquake-induced landslides,freezing and thawing-induced landslides,slope toe erosion-induced landslides and man-made induced landslides.The collapses areclassified into 2 categories:hard rock and soft rock collapses.Then,we deeply analyze and study the characteristics,mechanism and impossible hazard ways on the proposed railway engineering of the different types of typical landslides(e.g.Desha landslide of Baiyu county,Guchi village landlside of Jiangda county,Maoyanba landslide of Litang county,Arixia landslide of Baiyu county) and collapses(e.g.Wasigou collapse of Kangding county and Cuopu gulley collapse of Batang county).
