白山水电站于1976年10月截流,当时是采用的上下游双戗堤双向立堵截流方案,实际截流流量为118米~3/秒,最大落差为1.48米,最大流速为4.81米/秒;抛投石块总量约为2万米~3,最大抛投石块重约2.5吨。虽然截流难度、规模都不算大,但截流观测与模型验证情况有可供参考之处。故将截流设计概况、原型观测、模型验证和我们的几点体会介绍如下。 Baishan Hydropower Station closed in October 1976, when the double-embankment is used in the upper and lower reaches of the two-way vertical blocking closure plan, the actual closure flow rate of 118 m ~ 3 / s, the maximum drop of 1.48 meters, the maximum flow rate of 4.81 m / s; The total amount of cast stones is about 20,000 meters ~ 3, the largest cast stone weighs about 2.5 tons. Although the difficulty of interception, the scale is not large, but the closure of the observation and model validation are available for reference. Therefore, the closure of the design overview, prototype observation, model verification and some of our experience described below.
