本文的主要目的是研究混凝土面板堆石坝的面板脱空原因及脱空灌浆,本文将根据实例探究面板脱空灌浆方法,根据研究分析得出:堆石体、水位变化、施工因素、流体变形等因素是导致面板脱空的主要原因,为了有效避免面板脱空问题,必须加强施工规范,严格检查施工工序,加强施工管理,保证施工质量。
The main purpose of this paper is to study the cause of voidage of concrete face rockfill dams and the grouting of void. In this paper, the method of void-grouting of faceplates will be explored according to the examples. According to the research and analysis, it is concluded that the rockfill body, water level changes, construction factors, And other factors is the main reason leading to the emptying of the panel. In order to effectively avoid the problem of voidage of the panel, the construction specifications must be strengthened, the construction procedures strictly checked, the construction management strengthened, and the construction quality ensured.
