泄洪

Seasonal AR(1) models are first used to generate a great number of reservoir inflow flood. Next the triangle distribution and the normal distribution are applied to describe the uncertainty of spillways capacity.

应用一阶季节性自回归模型对入库洪水进行模拟，应用三角分布和正态分布描述水力不确定性对泄洪能力的影响，给定调洪起始水位和调洪规则，经过水库调洪演算，得到水库最高调洪水位随机分布和洪水漫顶风险率。

Bring forward optimum scheme of horizontal eddy flow discharge grotto in the right-bank of Gongboxia hydropower station, at the same time analyze the hydraulics characteristics of horizontal eddy flow discharge grotto in the Gongboxia hydropower station, for example flood discharge capacity、baffle ratio、exchange gas capacity、distribution of gas chroma、distribution of velocity of flow、average stress per time and distribution characteristics of fluctuation pressure and so forth.

提出了公伯峡水电站右岸水平旋流泄洪洞的优化方案，同时通过试验详细分析了公伯峡水电站水平旋流泄洪洞的水力学特性，如泄洪能力、消能率、通气量大小、掺气浓度分布、流速分布、时均压力和脉动压力分布特性等。

Tailing buildups on the river channel are very extensive and thick and have high contents of heavy metals such as As, Pb, Zn and Cd, which, in addition to directly jeopardizing the quality of water environment, has resulted in the decrease in the flood discharge capacity and increase in the flooded area.

河床上的尾砂沉积范围广、厚度大，重金属As、Pb、Zn、Cd含量非常高，除直接危害了水环境质量外，还造成河道泄洪能力下降和洪水淹没范围的扩大，构成时沿江土壤环境和生态环境的严重威胁。
