摘　　要：设计最高通航水位是船闸工程建设的关键技术参数之一,它直接影响船闸通过能力、建设工期和投资。针对株洲二线船闸工程设计最高通航水位取值的问题,根据株洲枢纽处洪水暴涨暴落、峰值历时短的水文特点,进行枢纽设计挡水位和不同重现期洪水历时分析,对船闸口门区通航水流条件、航道通航条件及不同特征水位时二线船闸工程投资情况进行论述,采用模型试验验证和测算投资比较的方法,得出“株洲二线船闸设计最高通航水位宜采用10a一遇洪水标准”的结论。该研究方法对山区、丘陵区枢纽扩建船闸工程具有借鉴意义。The designed highest navigable water level is one of the key technical parameters of ship lock construction,which directly affects the capacity,construction period and investment of the ship lock.For the value of the highest navigable water level of Zhuzhou second-line lock project design,we analyze the designed water level of the junction and the flood time in different recurrence periods according to the hydrological characteristics of the flood surge and collapse and the short peak time at Zhuzhou junction,and expound the navigable flow condition at the lock’s entrance area,waterway navigation condition and the investment of the second-line lock project under different characteristic water levels.Adopting the method of model test verification and investment calculation and comparison,we come to the conclusion that the highest navigation water level of Zhuzhou second-line lock design should adopt the flood standard once every 10 years.The research method can be used as reference for the lock expansion project in the mountainous and hilly areas.
