长江口横沙东滩典型海堤越浪量现场和试验研究
|
摘要
越浪量是允许越浪海堤设计的重要参数。在对以往相关研究成果进行回顾和分析基础上,结合长江口横沙东滩促淤圈围五期工程现场波浪和越浪量实测资料,通过对横沙东滩典型断面型式进行整体和断面物理模型试验,研究结构各参数对越浪量的影响,进而提出适合长江口海堤的越浪量计算公式。公式计算结果与试验数据吻合良好,与Van der Meer公式相比具有较好的一致性。
Wave overtopping rates are important factors in the design of seadikes. In the research,the field overtopping data of dikes of Hengsha enclosure project( Phase 5) in Changjiang Estuary were analyzed. Based on the existing research achievements and the dike structure characteristics and the wave conditions in Changjiang Estuary,2 D and 3 D physical model tests were carried out to study the influence of different factors on wave overtopping. The calculation formulas of the average overtopping discharge rate are presented,and the calculating results show good agreement with the experimental data and are consistent with those by the Van der Meer formulas.
