印尼西索肯抽水蓄能电站的下水库由碾压混凝土重力坝、溢流表孔和底孔组成；底孔的功能是在水库蓄水和正常运行时，为下游提供生态供水、灌溉流量和降低库水位。原底孔设计方案存在下闸封堵不落实等问题，故对其进行了替代方案的比较和论证；推荐采用加大进口竖井断面、增设闸门槽的设计方案。另外，为充分利用生态流量多发电，最终将底孔与小电站结合起来，经济效益明显。

The lower reservoir of Cisokon Pumped Storage Power Plant consists of RCC gravity dam, overflow surface outlet and bottom outlet.The bottom outlet is to release water downstream for ecology, irrigation and reservoir water reduction when the reservoir impounds and operates normally.In the original design of the bottom outlet, the potential risks of gate plugging not closed tightly may exist.There-fore, the alternative scheme is compared and argued.The design scheme of enlarging the shaft section at inlet and providing gate slot is proposed.Additionally, the bottom outlet and the lower installed capacity station are integrated to fully utilize the ecological flow for more power generation.This optimization results in outstanding economic benefit.
