摘　　要：在深厚覆盖层山区建水库,坝型多采用柔性坝,泄水建筑物宜采用岸边溢洪道,溢洪道边坡开挖、支护工程量大,投资高,对岸坡生态环境影响大。本文以贵州省施秉县黄金树水库为例,详细论述了溢洪道设计方案。经对比,决定采用溢洪道桩基方案。该方案投资少,施工简便、周期短,有利于工程尽快发挥效益和岸坡生态环境的保护,可在类似深厚覆盖层上的岸边溢洪道建设中推广使用。When the reservoir is built in the mountainous area with deep overburden layer, the dam type is mostly flexible dam. The spillway on the bank is suitable for the discharge building. The spillway slope excavation and support engineering quantities are large, the investment is high, and the impact on the ecological environment of the bank slope is great. Huangjinshu Reservoir in Shibing County of Guizhou Province is adopted as the support in the paper for discussing the design scheme of spillway in details. The spillway pile foundation scheme is adopted after comparison. The scheme has less investment, simple construction and short period, which is conducive for the project to exert benefits as soon as possible and protect the ecological environment of the bank slope. It can be popularized in the construction of the bank spillway with similar deep overburden layer.
