摘要
随着落成洲整治建筑物的建成,该区域内的流场将发生一定的变化,对船舶的航行及锚泊造成一定的影响,利用计算流体力学软件,数值模拟整治建筑物建成前后该区域内的流场变化情况。结果表明:整治建筑物的建成将有效地防止水流对落成洲的冲刷作用,航道水流更加稳定;但是,落成洲左汊下游镇江危险品锚地所在区域内的流速将明显提高,不利于锚泊安全,尤其是汛期。因此,应加强对该区域的监测和管理。
With building of regulating structure in Luocheng Shoal,the flow field distribution will be changed in this area,and it can have some effect on the navigation and berthing of ships.We apply the computational fluid dynamics software to simulate the flow field distribution of the area in this paper.The results show that the regulating structure can effectively prevent the erosion of the flow on Luocheng Shoal,and make the channel more stable.However,the water velocity of Zhenjiang dangerous chemicals anchorage will obviously increased,and the anchorage is located in the left branch channel of Luocheng Shoal.Especially in flood season,adverse affect of berthing will be produced because of the changes of flow field.So it is very necessary to monitor the flow field and manage the berthing ships.
