摘　　要：为实现电站提前发电,三岔河水电站大坝填筑及面板施工从原设计的一期施工优化为两期进行。通过合理地确定一期大坝施工高程、采用合适的填筑施工技术,大坝填筑及面板施工顺利完成。监测结果表明,大坝分期施工后二期填筑未对一期面板质量造成危害,一期面板混凝土质量、面板渗流量等参数满足设计要求。In order to realize the early generation of power station, the dam filling and face slab pouring of Sanchahe Hydropower Station are optimized from original designed whole-stage construction to two-stage construction. By reasonably determining construction elevation of dam in first stage and adopting suitable filling construction technologies, the dam filling and face slab pouring are successfully completed. The monitoring results show that the second-stage filling of dam does not cause any hazard to the quality of first-stage face slab, and the parameters of concrete quality and seepage of first-stage face slab meet design requirements.
