【摘要】 在研究碾压混凝土坝发展历史和趋势的基础上,提出一种新坝型,即将超贫胶结材料作为坝体填筑料,在上游面设置钢筋混凝土面板或沥青混凝土面板防渗,形成超贫胶结材料坝。介绍了超贫胶结材料坝的优越性和已有研究成果,认为超贫胶结材料坝的推广将带来良好的经济效益和社会效益,该坝型尤其适用于中小型水利水电工程。更多还原

【Abstract】 Based on the development process and trend of the roller compacted concrete dam,a new type of dam—the over lean cemented material dam was proposed.In construction of the new type of dam,the over lean cemented material was taken as the filling material,and the reinforced concrete face slab or asphalt concrete face slab was placed on the upstream face for seepage control.In this paper,the advantages and some research results of the new type of dam were introduced.It is considered that the dam type is suitable for medium-small water conservancy and hydropower projects,and it can bring great social and economic benefits.更多还原
