| 摘 要： | 龙口设置的主要目的是为了海堤安全度汛,往往设计过程中针对施工期度汛对上游排涝考虑不够周全,为合理解决施工期龙口设置对上游排涝的影响,结合象山道人山围涂工程龙口施工度汛对上游排涝影响分析情况,采用了潮波变形分析、和上游河网非恒定流洪水演进计算,提出了龙口合理设置方案,消除了龙口设置不合理对上游排涝影响,供广大围垦工作者参考。

| Abstract: | The main purpose of closure-gap setting is to make the seawall safe during flood.In the design of the closure-gap setting,however,the influence of the flood control during the construction on the upstream drainage is usually not well considered.In order to solve reasonably the influence of the closure-gap setting on the upstream drainage during the period of construction,a reasonable closure-gap setting scheme is put forward by using the tidal wave deformation analysis and the unsteady flow computation of upstream flood routing and combining with the analysis of the impact of the flood control during the closure-gap construction in the reclamation engineering in the Xiangshan Daoren Mountain on the upstream drainage,which may provide a reference for a large number of reclamation workers. |
