小湾水电站施工导流设计

Design of Construction Diversion for Xiaowan Hydropower Station

小湾水电站施工导流流量大，导流建筑物为永久建筑物，规模大、运行期长．施工导流设计研究了导流建筑物等级，施工时段划分，初、中、后期导流方式，导流程序，导流标准和导流建筑物的布置，以及第一台机组发电前的水库蓄水及满足下游工农业生产、生活用水要求等问题，进行了２００多个方案比较．

During the construction of Xiaowan Hydropower Station,the discharge of diverstion will be large,structures for construction diversion will be used as permanent ones so that they can be put into operation for a long time. Study has been made on their grades,time intervals,medes during the early, medium and later terms, procedures,standard, layout(which is broad in scale), reservoir impoundment prior to the commission of first unit,water supply for living and production of industry and agriculture. More than 200 schemes were compared.
