碾压混凝土技术,我国于1980年开始试验研究。由于这项新技术具有水泥用量少、施工速度快,相对降低工程造价等显著特点,所以,一经推广应用,发展就非常迅猛。而在我省对这项筑坝新技术尚属空白。另外,国内外采用这项新技术筑坝时,都用粉煤灰做掺合料,而我省今后待建的电站,都在粉煤灰供应地500km 以外。能否采用凝灰岩或其他炉渣等当地材料代替粉煤灰做掺合料,这是在我省推广这项筑坝新技术面临的新课题。中国水力发电工程学会派出三位专家(本文作者),于1992年3月参加了美国土木工程学会第三届碾压混凝土学术讨论会,回国后做了一次学术报告。本刊这期摘要选登这份报告,目的是引起同行们研究碾压混凝土筑坝技术的兴趣,以便推广这项筑坝新技术。加速我省水利、水电建设事业的发展。
RCC technology, our country began in 1980 experimental study. Because of this new technology with less cement consumption, construction speed, relative reduction of construction costs and other notable features, so once applied, the development is very rapid. In our province, the new damming technology is still blank. In addition, at home and abroad to adopt this new technology dam, are made of fly ash admixture, and our future power plant to be built, are in the supply of fly ash 500km away. Whether the use of local materials such as tuff or other slag instead of fly ash as admixture is the promotion of this new dam construction in our province, a new topic. China Hydropower Engineering Society sent three experts (author), in March 1992 to participate in the American Society of Civil Engineering, the third RCC Symposium, returned home and made an academic report. The issue of this issue is an abstract of this report, aimed at arousing peer interest in RCC dam technology in order to promote this damming technology. Speed up the province’s water conservancy, hydropower construction career development.
