摘　　要：龙滩碾压混凝土重力坝工程量巨大,最大坝高初期建设时为192m,最终为216.5m,技术难度大。设计中针对碾压混凝土施工特点,从枢纽布置、坝体结构、混凝土配合比、温控、施工方案等方面进行了深入的研究,形成了有特色的设计方案,实现了碾压混凝土连续快速施工。The Longtan Hydropower Project RCC gravity dam has a huge project quantity. Its initial maximum dam height during its early construction period is 192m and finally its height will be 216.5m so that its technical difficulty is big. In the design,we has conducted an in-depth study on its general layout dam body structure,concrete mix proportions,temperature control as well as construction scheme,etc,according to the characteristics of Rcc construction,so that we formed a featured design altematives and achieved continuous and fast RCC construction.
