摘　　要：锦屏一级水电站进水口处普斯罗沟沟口地形为近直立的陡坡,随着勘探工作的深入,勘测资料的充实,对进水口结构布置及其边坡进行了优化设计。优化调整后,进水塔前缘宽度缩窄了12 m,引渠内测边坡坡脚线也随之外移12 m,引渠边坡坡比优化为1∶0.18,由此边坡高度减小约100 m,降低了施工难度。优化设计中采用的"弱开挖,强支护"以及边坡动态设计原则,可供其他深切河谷高陡边坡河流段岸塔式进水口设计时参考。The intake of Jinping I Hydropower Station locates on the outlet of a ravine with a nearly upright slope.With the increase of geological investigation,the intake structure and layout and the slope design were optimized.The front width of intake reduces 12 m,the toe line of inner slope of diversion canal moves outward of 12 m and the slope ratio is optimized to 1 ∶ 0.18.As a result,the slope height reduces about 100 m.The principle of ＂weak excavation,strong support＂ and dynamic design of slope in design optimization can be as reference for similar hydropower project.
