淤泥质海岸后方大面积的低地平原主要通过海岸上建设的涵闸排水,潮滩匡围对沿海涵闸排水的影响是围垦工程必须解决的问题。文章以条子泥西侧岸滩仓东片匡围为例,探讨了不同堤线方案下邻近闸下流槽各种落潮水量组成及其维护闸下排水能力的有效性。结果表明,合理的滩涂匡围堤线方案,在平均潮汛及一般大潮汛时对邻近闸下排水能力影响较小,而在风暴潮或秋季大潮汛时有一定影响,但可以通过若干次冲淤保港来解决。
The large area of lowland plains behind the muddy coast mainly discharges the culvert through the coast. The impact of the tidal flat on the culvert of coastal culverts is a problem that must be solved in reclamation projects. In this paper, taking the Kuandu section of the east coast of Shitangcang on the west side of the slime mud as an example, the author discusses the composition of various ebb tides in the adjacent sluice trough under different embankment schemes and the effectiveness of the drainage under the sluice gates. The results show that reasonable tidal flat line project of Tidal Flat Riverbank has less influence on the drainage capacity of the adjacent floodgate during the average flood season and the general tidal flood season, but has some influence in the storm surge or the autumn tide flood season. However, Paul to solve.
