Type choice of gates is an important work of barrage construction. By computing and analyzing
we obtain the following results: ①comprehensively considering various aspects such as terrain
geology
watercourse and construction etc
an open-flat- bottom barrage with plane gate and stationary hoisting device should be chosen; ② the length of the axis of a barrage should be 626 m. As an open flat barrage
the bottom board elevation is 579.9 m and 29 gate openings will be set up; and the size of each gate openings will be 19×4.1m (width x height).
