摘要
堆石混凝土技术是在自密实混凝土技术上发展起来的一种新型大体积混凝土施工技术,具有低碳环保、低水化热、工艺简便、造价低廉、施工速度快等特点。堆石混凝土技术在水利水电工程次要建筑物上已有较多应用,但在大中型水电工程挡水大坝等主要建筑物上应用较少。简述了堆石混凝土技术的主要特点,分析了该项技术目前的应用情况和存在的问题,介绍了堆石混凝土在吉牛水电站右岸挡水坝中的应用情况,将有助于该技术的总结和推广。
Rock-filled concrete technology is a new mass concrete construction technology on the base of selfcompacting concrete,with low carbon green,low hydration heat,simple process,low cost,fast construction,etc. Rock-filled concrete technology has been more used in water conservancy and hydropower engineering secondary structures,and less used in the main structures of hydropower engineering,such as retaining dam.This paper describes the main features of rock-filled concrete technology,analyzes the current application of this technology,describes the application of rock-filled concrete technology in Jiniu hydropower station retaining dam. This will help to summarize and popularize the technology.
