糯扎渡水电站枢纽建筑物边坡工程设计

糯扎渡水电站工程规模巨大，枢纽区地质条件复杂，建筑物开挖边坡高，稳定性较差。通过对各建筑物边坡的影响分析并参照有关规范和已建工程的经验，提出了边坡的控制标准。在地质勘察的基础上，进行边坡失稳模式判别，二、三维极限平衡和平面有限元分析，提出边坡的综合加固处理措施，解决了枢纽区复杂地质条件下的高边坡稳定及支护问题。

Slope project design of Nuozhadu Hydropower Station's layout structures

The scale of Nuozhadu Hydropower Station is huge but its geologic conditions at site are complex, with the high side-slope and poor stability. Based on analyzing the influences on the slope of the structures and referring to the experience of some finished projects, the controlling criterion is put forward in this paper. On the basis of geologic explorations, the mode of slope failure was judged, and 2D or 3D limit equilibrium analysis and planar finite element analysis methods were carried out. The comprehensive supporting and reinforcing measure for side slope was recommended and the stability and reinforcement problems of high slope with complex geologic condition were solved.
