摘　　要：某水电站属高山峡谷地区,由于地形、地质条件复杂,江面宽窄特征不明显,前期移民难度大,施工导流设计的难度较大,采用常规的施工导流方式不能取得满意的效果。结合工程特点,通过采用一次拦断与分期拦断组合导流方式,达到了枢纽布置较优、费用节省、工期短、前期移民难度降低等目的。A hydropower station locates in mountain area. Because of complex topographical and geological conditions, unobvious width characteristic of riverbed at dam site, and difficult early resettlement, the design of construction diversion is more difficult and conventional construction diversion method cannot achieve satisfactory results. Based on the characteristics of project, a new diversion method of first stop and staged block combination diversion is used, which can optimize structure layout, save costs, shorten construction duration and reduce the difficulty of early resettlement.
