Mike21-BW在游艇码头平面规划布置中的应用

Application in layout of yacht wharf based on MIKE21-BW

随着国内游艇码头建设的不断增加,游艇码头港内泊稳条件得到了越来越多的关注。影响游艇码头港内泊稳的主要因素有防波堤的布置、防波堤的结构形式、港内护岸的结构形式等。基于MIKE21-BW模型,以长岛县南长山岛规划建设游艇码头为例,对游艇码头港区的两种布置方案、6个浪向作用下的港内泊稳情况进行了数值模拟。对比两种平面布置方案口门处及港内游艇泊位处波高,分析影响游艇码头港内泊稳的影响因素。结果表明,防波堤位置、口门处防波堤的结构形式及港内陆地护岸的结构形式对游艇码头港内泊稳条件有直接影响。

With the continuous increase of the construction of domestic yacht wharf,more and more attention has been paid to the berthing conditions in the harbor.The main factors affecting the mooring stability of yacht wharf are the layout of breakwater,the structural type of breakwater,and structural form of revetment in the harbor.Based on the MIKE21-BW model,taking the planning and construction of yacht wharf on south Changshan Island in Changdao County as an example,mooring stability in harbor under two layout schemes of yacht wharf and six wave directions are simulated numerically.Comparing the wave heights at the entrance and the yacht berth in the harbor of two layout schemes,this paper analysis the factors affecting the stability of yacht berth in the harbor.The results show that the location of the breakwater,the structural form of the breakwater at the entrance and the structural form of the inland revetment have a direct impact on the berthing stability conditions of the yacht wharf.
