在大渡河枕头坝一级水电站过鱼设施设计过程中，对河中鱼类分布情况和坝址区的地形地质条件进行了充分研究。结果表明，建坝影响河段没有江海洄游和长距离洄游鱼类，只有本土鱼类，通过修建过鱼通道可以减缓电站建设对鱼类上下游迁移交流的影响，保护鱼类遗传特性。在利用水工模型分析水库大坝上下游水流流场并考虑两岸水工建筑物布置情况的基础上，结合地形条件，设计了过鱼通道的坡度、进出口、梯身、池室等。实现了既不影响河岸边坡稳定，又功能可靠、运行稳定的目的。

In the design research of fishpass facilities of Zhentouba I Hydropower Station, the fish distribution and geological condition at the dam site area were researched. The research result showed that no river-sea and long distance migratory fish ex-isted in the dam construction reach, but only local fish here and the fishpass building can reduce the influence on upstream-downstream fish exchange and protect fish heredity. Based on the analysis of flow fields at upstream and downstream of the dam by using hydraulic model and in consideration of hydraulic structure layout on both banks, the fishpass slope, inlet and outlet, channel body, fish pond etc. are designed according to the landform condition,. The fishpass functions well and has no influence on side-slope stability.
