摘要 潜堤高程是淤泥质海岸潜堤设计的关键要素之一。为了确定潜堤高程,首先根据已建潜堤工程的经验分析得出潜堤减淤的主要机理,即主要是阻挡了浮泥或底部高含沙水体直接进入航道和缩短了含沙水体进入航道的时间,进而在长水槽中开展了一系列比对实验,主要研究不同堤顶高程时的水流紊动、堤前浮泥起动、浮泥层厚度变化、堤后航道泥沙落淤情况等,并以此作为比选堤顶高度的基本依据。实验结果表明当相对高度即潜堤高度与堤前水深之比为0.2~0.5时,便有较好的减淤效果。 The height of submerged dike employed to diminish sedimentation in muddy coast is one of important factors for the design. The experiments conducted in a long flume are designed based on the main principle of using the submerged dike to eliminate sedimen- tation, which is to prevent fluid mud from entering the channel directly, and shorten the time of high silt-laden water entering the chan- nel. The flow disturbing, motion of fluid mud, depth variation of fluid mud and siltation in the channel behind the submerged dike are selected as the main parameters for the comparison of different heights of the dike. The results show that the submerged dike is efficient to decrease the erosion of fluid mud existing in front of the dike when the relative height, the ratio of height of dike to water depth, equals to 0.2 - 0.5.
