摘要
根据那吉枢纽库区水位纵向分布和航道治理工程特征,建立了库尾河段数学模型。依据施工设计阶段、竣工验收阶段相关资料以及竣工3 a后治理河段实测地形资料,结合数学模型计算成果,对库区航道治理效果进行了分析。分析表明:施工位置与设计相符;竣工后航道水深、航宽、曲率半径等指标满足航道设计尺度要求;与设计施工地形相比,竣工3 a后,开挖位置未发生淤积现象,航行水域非开挖区河床高程低于航槽设计底高程。综合分析,工程整治效果达到航道设计目标。
Based on characteristics of longitudinal water level and channel regulation project in reservoir reach of Naji junction,this paper establishes the orthogonal curve two-dimensional current mathematical model for the reservoir tail reach,and analyzes the channel regulation effect for the reservoir reach according to materials of the design stage,acceptance stage and topography after 3 years of completion,as well as the calculation results by mathematical model.The analysis shows that construction site is consistent with the design;the channel dimension and curvature radius of the waterway conform to the design dimensions’requirement;no siltation occurs 3 years after completion,and the elevation of the unexcavated area is lower than that of the excavated area.In a word,the channel regulation effect meets the design goal.
