一、前言 70年代以来,随着水电建设的飞速发展,国内外都在探索混凝土坝体浇筑的新施工方法,以求降低造价,加速施工进度,缩短水电站的建设周期。碾压混土筑坝法(即RCD施工法)是国外近十几年来研究成功并已达到实用要求的一项新的混凝土筑坝施工技术。近年来,我国水电部的有关单位也在不断地对此项技术进行研究、试验、并取得了可喜的成果。国外在采用RCD法施 I. INTRODUCTION Since the 1970s, with the rapid development of hydropower construction, new construction methods for concrete dam concrete pouring have been explored at home and abroad in order to reduce the cost, accelerate the construction progress, and shorten the construction period of hydropower stations. The roller compacted concrete construction method (ie RCD construction method) is a new concrete dam construction technology that has been successfully researched and has reached practical requirements in recent decades. In recent years, the relevant units of China’s Ministry of Water Resources have also continuously conducted research and experiments on this technology and achieved gratifying results.
