| 摘 要： | 根据小南海枢纽河段河势及水流条件特点,通过水工模型试验和船模试验相结合的方法,分析了小南海枢纽施工二期导流明渠通航条件及存在问题,提出了明渠进口段炸除碍航礁石、出口段开挖新航槽的优化方案。研究表明:导流明渠原设计方案明渠进、出口段礁石碍航严重,通航水流条件差;优化方案通过整治措施显著改善了导流明渠的通航条件,保障了小南海枢纽施工二期长江上游航运的安全畅通。

| Abstract: | According to river regime and flow condition characteristics of Xiaonanhai Water Control Project reach,diversion channel navigation condition and existing problems in construction phase Ⅱ are studied by hydraulic model and ship-model test.Generally,navigation flow condition is bad because of the rocks at the import and export section of diversion channel in original diversion channel design,and has been significantly improved in optimization scheme by regulation the import and export section of diversion channel and excavation new channel. |
