基于RCD碾压混凝土坝坝体渗漏的探究

Research of Seepage for RCD Roller Compacted Concrete Dam

我国水利资源比较丰富。而开发和利用水利资源,需要建设水坝来调节水流量,提供水力发电,灌溉农田。水坝的建设,能够促进我国经济的发展,也给我国人民带来了诸多的便利。但是,在水坝的建设中,由于坝体差的缘故,容易出现渗漏现象。特别是我国水利设施使用RCD碾压混凝土坝坝体,时常发生局部渗漏现象。文章就此探究了RCD碾压混凝土坝坝体出现渗漏现象的原因,提出了防治水平施工缝渗漏的方法,并对坝体薄弱部位、裂缝部位的形成进行分析,从而得到解决混凝土坝坝体渗漏的方法和措施。

China＆#39;s rich water resources comparatively.It is needed to build dams to adjust the water flow for the development and utilization of water resources , to provide hydroelectric power , to irrigate farmland ,The construction of a dam can promote the development of our national economy , it also has brought many conveniences to the people of our country.However ,leakage phenomenon often happens in the construction of the dam due to the poor dam quality.Especially partial leakage phenomenon often appears for the RCD roller compacted concrete dam and water conservancy facilities in China.This paper probes into the reasons why RCD roller compacted concrete dam leakage phenomenon happens , the method of construction controlling horizontal joint leakage ,and the weak dam body place and cracks forming are analyzed in order to get the solutions and measures of concrete dam leakage protection .
