摘　　要：通过天山公路溜砂坡病害形成条件和影响因素的分析,依据野外观察和室内试验数据,提出了溜砂坡坡体失稳的动力学机制及形成演化规律;同时以K612+750～K613+850特大溜砂坡群为例,对该溜砂坡群的变形破坏机理进行了分析,并基于模糊数学理论及层次分析法对该溜砂坡的危险性进行了模糊评判,提出了治理溜砂坡的初步对策。Through the analysis of causes and influencing factors of sand-sliding slope along Tianshan Highway, both the dynamic mechanism and the formation and evolution laws of instable body of sand-sliding slope are proposed on the basis of outdoor investigation and indoor experimental data; at the same time, taking K612 ＋750 - K613 ＋ 850 extra large sand-sliding slope for example, the analysis of deformation and damage mechanism thereof is conducted and the fuzzy evaluation against the hazard is carried out on the basis of fuzzy mathematics theory and by means of analytic hierarchy process, thus the initial treatment countermeasures are proposed.
