| 摘 要： | 分别对连云港港30万吨级航道扩建工程的两种有防波堤方案及无防波堤方案进行了工程前后平面二维潮流泥沙的数值模拟.利用窦国仁悬沙不平衡输沙方程及河床变形方程式,进行了正常天气和台风天气下的航道底部淤积计算,比较分析了3种方案对航道淤积的影响.模拟和计算结果表明,有防波堤方案1在防浪挡沙方面要优于其它两个方案,是较为合理的防波堤布置方式.

| Abstract: | A two-dimensional simulation on tidal flow and sediment was conducted on three schemes of 300 000DWT channel extension projects,two with breakwaters and one without breakwater,in Lianyungang Port.The influences of the projects on channel siltation are compared and analyzed based on the calculation of siltation using Dou Guoren's non-equilibrium suspended-sediment transport equation and riverbed deformation equation,during normal weather and typhoon season.The results show that the first project with breakwaters has better abilities in wave protection and sand prevention than the other two,and its layout of breakwaters is more rational. |
