摘要

摘要: 为了解决围堰施工进度和料场征地移民进度之间的矛盾,在邕宁水利枢纽工程施工阶段提出了一期枯水围堰设计方案的替代结构型式,并利用施工仿真、技术经济分析方法对围堰型式进行了优选;采用三维数值模拟和物理模型试验方法研究了束窄河床水力特性,结果表明,当纵堰轴线布置在坝体7号至8号闸墩之间时,能够解决施工期通航和围堰防冲问题。研究结果为本工程一期枯水围堰施工提供了重要依据,对于保证工程施工进度起到了决定性作用。

Abstract: To solve the contradiction between the cofferdam construction progress and the material land requisition and resettlement,the alternative solutions of the designed scheme is proposed during the construction of Yongning water control project 1 st stage cofferdam of the dry season,optimized by construction simulation,technical and economic analysis methods. The hydraulic characteristics of the narrowed riverbed are investigated by 3 D-numerical simulation and physical model test methods. The results show that when the axis is arranged between7# and 8# gate pier of the dam body,the problem of navigation and scour prevention for the cofferdam can be resolved. The results provide an important basis for the construction of the 1 st stage cofferdam of the dry season,thus decisively ensuring the construction progress of this project.
