摘　　要：Most of the flood from the wide inner lowland plain discharges through tide locks on coast, and the influence of tidal flat inning projects on the tide lock drainage must be solved by seawall line choice. Taking the Cangdongpian inning area on the west side of Tiaozini Sand as a case study, the paper analyzed the compages and validity of ebb tide water to maintain the flood discharge creek below the tide lock for different projects of seawall line. Result indicates that a rational seawall line program has little influence on the flood discharge of lock during the mean tide or general spring tides, but has certain influences during a storm surge or an extreme spring tide in autumn. However it could be resolved by several times of artificial scour on the creek.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。
