| 防波堤掩护水域的泊稳条件对船舶进出港以及靠泊作业的安全性具有显著影响，如何精准模拟堤后的波高分布对工程设计具有重要意义。通过试验和数值模拟方法，深入探讨扭王字块护面的防波堤后泊稳条件。在物理模型试验的基础上，采用基于非静压方程的SWASH模型，对工程区域的波高分布进行数值模拟，在SWASH模型中，扭王字块防波堤通过孔隙层、地形与孔隙层结合以及等效底摩阻系数等3种方法进行表示。采用基于Boussinesq方程的MIKE 21 BW模型对工程实际区域的波高分布进行数值模拟，并与非静压模型的结果进行比较。结果表明，在实际工程中的港池泊稳研究方面，基于非静压方程的SWASH模型中的等效底摩阻系数方法更具优势和适用性。 |

| The mooring stability conditions of breakwater cover waters have a significant impact on the safety of ships entering and leaving ports and berthing operations.How to accurately simulate the wave height distribution behind the breakwater is of great significance to engineering design.By means of test and numerical simulation,we discuss in depth mooring conditions behind the breakwater with an armor layer of accropode.Based on the physical model test,we use the SWASH model based on the non-hydrostatic equation to numerically simulate the wave height distribution in the engineering area,and represent the accropode armored breakwater by three methods in the SWASH model,such as the accropode armored breakwater passing through pore layer,topography and pore layer combination and equivalent bottom friction coefficient.Then we use the MIKE 21 BW model based on Boussinesq equation to simulate the wave height distribution in the actual engineering area,and the results are compared with those of the non-hydrostatic model.The results show that the equivalent bottom friction coefficient method in the SWASH model based on the non-hydrostatic equation is more advantageous and applicable in the study of harbor basin mooring stability in practical engineering. |
