| 摘要: |
| [目的]研究码头本身结构形式对港内波高分布及越浪量的影响。[方法]通过整体物理模型试验,以某码头扩建工程为例,对比分析了普通沉箱码头及开孔沉箱码头港内波高分布以及不同面高程下的越浪量。[结果]开孔沉箱码头在减小港内波高及越浪上相比普通沉箱码头更有优势;码头面高程是影响越浪量的重要因素。[结论]为有效地控制港内波高及减小码头越浪量,工程中可优先考虑采用具有良好消浪性能的开孔形式码头,同时在经济技术可行的条件下尽可能地提高码头面高程。 |

| Abstract: |
| [Objective] By overall physical model test, the harbor wave height distribution and the wave overtopping of different wharf structural forms were studied.[Methods] With the example of one wharf extension project, the wave heights in harbors and the wave overtopping in different wharf surface elevation were compared between ordinary and perforated caisson wharf.[Results] The results show that the perforated caisson wharf has more advantages to controlled the harbor wave height and reduced the wave overtopping than ordinary caisson wharf.The wharf surface elevation is an important influence factor in wave overtopping.[Conclusion] In order to reduced harbor wave height and wave overtopping, the perforated caisson wharf, which has good characteristics of dissipating waves, should be preferentially considered to use, meanwhile the wharf surface elevation should be increased as much as possible under economic conditions available. |
