摘　　要：水电站施工初期导流阶段,在风险一定时,若能延长主汛施工时段,一般而言,势必缩短工程建设周期。光照水电站大坝在2006年主汛期施工期间,采用上游实测天然来水量、导流洞过流量、上游水位、围堰以上库容调蓄量等实测参数进行水力计算,加高了上游围堰,相应提高了挡水标准,成功抵御了2006年四场洪水的侵袭,为工程建设赢得了四个月的宝贵施工时间。At the initial construction diversion stage of hydropower station, when risk is certain, the project construction period will be shorted if the main flood period is enlarged. In the main flood period, the dam for the Guangzhao Hydropower Station adopts the upstream measured natural inflow, discharge from diversion tunnel, upstream water level, capacity regulation of the reservoir in upstream of cofferdam and other actual measured parameters to make hydraulics calculation. The upstream cofferdam has been enhanced and the water retarding standard has been raised, which successfully fights against four floods in 2006 and wins the four-month construction time for the project.
