近代世界各国的坝工建设中,堆石坝和土坝的比重愈来愈大。据1977年统计,国外高于15米的12517座坝中,土石坝占了96％。在土石坝蓬勃发展的同时,岩土力学和施工方法都有了长足的进步。正是伴随着施工方法的重大变革,在六十年代末出现了一种新的堆石坝——钢筋混凝土面板堆石坝(以下简称面板坝,英文缩写为CFRD)。这种坝型具有其他坝型无可比拟的优点,因而发展迅速。许多坝工专家都认为,它代表了堆石坝的发展方向,是坝工建设技术的一大突破,具有广阔的发展前景。本文拟对此坝型的特点、发展概况和设计方法等作一简要介绍。
In modern dam construction in all countries, the proportion of rockfill dam and earth dam is getting bigger and bigger. According to statistics in 1977, out of 12,517 dams higher than 15 meters abroad, earth-rock dams account for 96%. While earth and rock dams are booming, both great advances have been made in geotechnical mechanics and construction methods. It is with the significant changes in construction methods that a new rockfill dam, a concrete faced rockfill dam (CFRD) has emerged in the late 1960s. This dam has the unparalleled advantages of other dam type, so the rapid development. Many dam experts believe that it represents the development direction of rockfill dam, dam construction technology is a major breakthrough, with broad prospects for development. This paper intends to make a brief introduction to the characteristics, development profile and design method of this dam type.
