混凝土面板在碾压式重力坝中的错位分析研究

Dislocation Analysis of Concrete Slab in Roller Gravity Dam

混凝土面墙技术在混凝土重力坝中的应用可降低工程造价,施工期可节省模板、缩短层间间隔,所以对面墙应力变形及错位接触的稳定性研究十分重要。文章结合实际工程,分析蓄水期不同荷载组合的混凝土面墙和大坝的面-面接触,通过不同接触面的错位分量计算结果表明混凝土面墙作为碾压混凝土重力坝的防渗层,其应力变形符合设计规范要求。

The application of concrete wall technology in concrete gravity dam can reduce the project cost,save formwork and shorten the interval between floors during construction,so it is very important to study the stability of stress,deformation and dislocation contact of the wall.Based on the actual engineering,this paper is to analyze the surface-surface contact between concrete wall and dam under different load combinations during impoundment period,the calculation results of the dislocation components of different contact surfaces show that the stress and deformation of the concrete wall as the impermeable layer of RCC gravity dam meet the requirements of the design code.
