| 摘 要： | 无口门式潜堤蓄泄系统中水流属于非恒定流,其蓄泄问题以及堤后坝田内的水位问题关系到潜堤的保滩促淤效果以及堤身的结构稳定性,外海潮位的交替变化对潜堤蓄泄系统的非恒定流调节影响较大,其蓄泄特征较复杂,文中以水量平衡原理为基础,结合外海潮位特性,建立不同情况下坝田内水位变化的解析方法,通过对工程实例计算验证,分析不同的潜堤方案对坝田内水位的影响,结果表明,该方法可以合理地模拟潜堤后坝田内的水位变化过程.

| Abstract: | The flow of a non-gap submerged dyke system is unsteady,the sluice and water level of the dams area have a close relation to the effect of beach protection and siltation promotion of the submerged dyke and the structural stability of dams.The alternation of tide has great influence on the unsteady flow,and the character of sluice is complex.Based on the water balance principle and according to the tide character,an analytic method was worked out to analyse the changes of water level in different circumstanc... |
