摘　　要：高原地区生态比较脆弱,容易受到外界影响失去平衡,而公路滑坡是导致生态失衡的主要因素,因此在高原地区查清公路滑坡的原因并进行生态治理显得尤为重要。在青海省某公路滑坡成因分析中,对滑坡带土的C值、φ值、河水位变动、施工开挖的影响等因素进行分析,确定最大影响因素为φ值,用反演法选取土的C、φ值。采用减载反压和生态化护坡的方案进行治理,时间证明该方案效果良好。The ecology in high altitude area is week and easily lost balance with the external influence and the highway landslide is the main factor of the ecology unbalance.Therefore,it is very important to investigate the causes of highway landslide of high altitude area and to conduct ecological management.In the analysis of landslide causes of certain highway of Qinghai province,we analyzed the factors of C value,φvalue,water level fluctuation of river,and influence of excavations and confirmed that the biggest factor is φ value and applied inversion method to choose the C value and φ value.The ecological management adopted deloading counter pressure and ecological slope protection scheme and time has proved its good effectiveness.
