摘　　要：本文通过模型试验对山坪电站一期和二期导流建筑物布置方案的合理性进行系统研究。研究认为,无论一期明渠导流还是二期泄洪闸导流均能满足工程泄流设计要求,上下游围堰高程设计合理,下游河道水深满足通航要求。研究同时提出了一期明渠导流防护部位以及调整泄洪闸下游消力池尺寸的建议和泄洪闸进口左导墙优化体型,为工程优化设计提供了重要技术支撑。The rationality of the layout of the diversion buildings in the first and second phases of Shanping Power Station is systematically studied through model tests in the paper.The results show that the diversion of the first stage open channel and the second stage spillway gate can meet the design requirements of the project discharge.The elevation design of the upstream and downstream cofferdams is reasonable,and the water depth of the downstream channel meets the navigation requirements.Meanwhile,some suggestions are put forward for the first stage open channel diversion protection areas,adjustment of spillway sluice downstream drain tank and optimized shape of the left guide wall at the entrance of the spillway sluice,thereby providing important technical support for the optimal design of the project.
