与三峡工程一样,向家坝水电站为混凝土重力坝,主要靠自身重量维持大坝的稳定。向家坝大坝设计坝长896米、最大坝高162米。因地质条件复杂,出于坝基抗滑稳定考虑,向家坝大坝底部设计宽达164米,大坝“身高”与“腰围”相当。体型像个大“胖子”的向家坝大坝设计混凝土浇筑总量约1400万立方米。在这1400万方大坝主体混凝土浇筑中,绝大部分是在二期工程中完成的,即右岸非溢流坝段、泄洪坝段、厂房坝段和升船机坝段的混凝土浇筑。“向家坝大坝混凝土浇筑真正只有3年时间!”在向来宾介绍工程情况
Like the Three Gorges Project, Xiangjiaba Hydropower Station is a concrete gravity dam, which mainly maintains the dam’s stability by its own weight. Xiangjiaba dam design dam length 896 meters, the maximum height of 162 meters dam. Due to the complex geological conditions, due to the stability of dam foundation, the bottom of Xiangjiaba dam is designed to be 164 meters wide, and the dam “height ” is equivalent to “waistline ”. Body shaped like a big “fat ” Xiangjiaba dam design pouring a total of about 14 million cubic meters of concrete. In the concrete construction of the main body of 14 million square meters, most of them were completed in the second phase of project, namely, the right bank non-overflow dam section, flood dam section, factory dam section and shiplift section concrete pouring. “Xiangjiaba dam concrete pouring really only three years!” In introducing the project to the guests
