一、前言恶滩水电站位于红水河忻城县境内。红水河是一条峡谷型河流,洪枯流量相差达100～200倍,洪枯水位相差40～50米,因而给水电站厂房设计带来较大的困难。例如厂房围护结构往往做得很高很厚;四周封闭挡水,不能开窗,通风照明全靠人工;进厂设备靠垂直提升。水电站厂房围护结构的平面布置,一般呈矩形。 I. Preface Eitan Hydropower Station is located in Xincheng County, Hongshui River. Hongshui River is a canyon-type river, with a difference of 100-200 floods and floods, and a difference of 40-50 meters between flood and flood water levels, which brings great difficulties to the design of powerhouse. For example, the enclosure structure of the factory is often made very high and very thick; water and water are enclosed and can not be opened all around, and ventilation and lighting are all based on manpower; Hydropower plant building envelope layout, generally rectangular.
