Study on Zecheng Xi'an Hydropower Station(Phase II)Engineering Construction Diversion Scheme in Shanxi Province

Aimed at the characteristics of the second phase of Xi'an hydropower station，and on the basis of the Specifications for Construction Planning of Water Resources and Hydropower Engineering(SL303-2004)，this paper determined the diversion standards of the dam construction project，and came up with three diversion schemes：once-in-a-decade flood standard for all year round，once-in-a-decade flood standard for non-flood season and the water flow through the dam body，once-in-a-decade flood standard for non-flood season and the water doesn't flow through the dam body，and then makes comparison and selection of these three schemes and finally determined using the non-flood season and the water doesn't flow through the dam body.
