建造在宽阔的矩形河谷上的坝是由30个分段组成。每一段都是带有重力式垛头的双垛(图1)。分段宽25米,迎水面和背水面的边坡都是1:0.50平面图上,沿坝轴线元孤的半径为1,000米。大部分坝段高度相等,即在基础以上 H=112米。坝身混凝土标号是 M150,200和250.平 The dam built on the wide, rectangular valley consists of 30 segments. Each section is a double stack with a gravity head (Figure 1). Sectional width of 25 meters, facing the water and the slope of the back of the water are 1: 0.50 plan, along the axis of the Yuan Yuan solitary radius of 1,000 meters. Most dam sections are equal in height, ie above the foundation, H = 112 meters. Dam concrete is numbered M150,200 and 250. Flat
