摘　　要：彭水水电站大坝为弧形碾压混凝土重力坝,最大坝高116.5 m。大坝泄洪采用全表孔方案,溢流坝段表孔以下采用碾压混凝土,碾压混凝土总量58.76万m3,占坝体混凝土总量的58%。大坝采用全断面碾压混凝土经济断面。对大坝的应力、混凝土配比设计防渗方案等进行了介绍,分析大坝结构布置尽量简化,在无地质缺陷部位采用找平混凝土封闭法固结灌浆等结构措施,以达到碾压混凝土快速施工的目的。Pengshui dam is an arched RCC gravity one with the maximum dam height of 116.5 m.The top openings are designed for flood release and the dam body under the top openings is RCC with its volume of 587.6 thousand m^3,accounting for 58% of total dam concrete volume.The overall RCC economic cross-section is designed for the dam.This paper presents the stress analysis, concrete mix ratio,seepage control scheme and the simplification of dam structure layout.The foundation consolidation grouting with levelled concrete layer plugging is adopted for geologic defect-free position to realize quick RCC construction.
