摘　　要：金沙江乌东德水电站坝址区边坡高达1 000m,属特高工程边坡,对工程有重大影响。本文有针对性地从坝址区地应力场分布特征及其对工程高边坡的影响、高边坡整体稳定性以及局部稳定性等方面对坝址区工程特高边坡的稳定性进行了系统研究。研究表明,高边坡稳定性较好,对不稳定块体应及时采取锚杆及预应力锚索支护处理。At Wudongde Hydropower Station dam site the slope height reaches 1000m, belongs to extra -high slopes. It has great influence on the project. In this paper,according to the dam site area in situ stress field characteristics and their impacts on the extra--high slope, the slope integral stability and local stability are analysed systematically. The analysis indicates that as a whole the high slope is rather stable but locally the unstable rock blocks shall be timely treated with rock bolts and prestressed cables.
