| 摘 要： | 在帕隆藏布北岸的川藏公路上,有许多冰碛高陡切坡.这些冰碛切坡具有独特的结构力学特征,其几何形态(高度与坡度的组合值)不同于一般经验值的范围.根据其物理力学性质,采用圆弧法对边坡进行稳定性分析,取得了与实际相符的结果.

| Abstract: | There are many moraine slopes which are high and steep along the north bank of Purlung Tsangpo River because of construction of Sichuan-Tibet Highway. Their character of structure and mechanics is specific, and the acknowledgement of the combination of cut-slope height and angle is broadened. The arc method is applied to analyze stability of the slopes, and the outcome accord with the fact. |
