概述碾压混凝土是七十年代以来世界上还刚开始的一种浇筑混凝土坝的新技术。日本于1974年成立了“混凝土坝合理化委员会”,专门对混凝土重力坝的合理施工方法进行研究。1976年首先在大川坝的围堰上进行了大规模的碾压混凝土试验性施工,1979～1980年在大川坝坝体基础底板(图1)、1978～1980年在岛地川坝(图2)、1980年在新中野坝的消能工基础 Overview Roller compacted concrete is a new technique of pouring concrete dams that has just begun in the world since the seventies. Japan established the Concrete Batching Commission in 1974 to study the reasonable construction method of concrete gravity dam. In 1976, a large-scale RCC trial construction was carried out on the cofferdam of the Da Chuan Dam. From 1979 to 1980, the base plate of the Da Chuan Ba ​​dam body (Figure 1) and the Chuanchuan dam from 1978 to 1980 (Figure 2 ), In 1980 in Xinzhongyoba energy dissipater foundation
