喜河水电站施工导流

On the Construction Diversion of Xihe Hydropower Station

汉江洪水峰高量大、陡涨陡落,年内最大洪枯比达600倍,坝址地形左陡右缓,施工导流采用分三期导流的方式,施工导流程序复杂。

The floods of the Hanjiang River have the features of high peak flow with abrupt rise and recession process. Its ratio of high flow to low flow is as high as 600. The topography of dam site is steep on the left bank, but mild on the right. So that the construction diversion were divided into three phase, each with complicated procedure.
