连拱薄壁堰是在连拱坝和迷宫堰基础上发展演变而产生出来的一种新堰型,是由一系列支墩和盖板所组成,支墩沿坝轴线排列,前面设盖板,形成挡水面。水压力由盖板传给支墩,再由支墩传递到地基。盖板为一系列倚在支墩上的拱筒,与支墩组成整体结构。连拱薄壁堰具有结构简单,投资省,效益大,管理方 The double arch weir is a new type of weir produced by the evolution and evolution of the arch dams and the labyrinth weir. The weir consists of a series of supports and cover plates. The abutments are arranged along the axis of the dam with the front cover , Forming a water retaining surface. Water pressure is transmitted from the cover plate to the pier and then to the foundation by the pier. Cover a series of leaning on the piers on the arch, and the pier constitute the overall structure. Even with thin arch weir has a simple structure, investment, efficiency, management side
