大连港某公共航道平面布置

Plan layout of a public waterway of Dalian Port

航道平面布置受地形、地质、潮流以及周边环境条件等因素影响较大。以某公共航道工程为实例,采用潮流泥沙数学模型试验和船舶操纵试验等方法,从工程区域自然条件、工程与环境保护区的关系以及港口中远期发展规划等方面对航道平面布置进行分析论证,确定最优轴线方案。并论述航道尺度确定时的设计创新内容,为综合制约因素较多的类似长里程航道项目平面布置提供技术参考。

The channel layout is greatly affected by topographic and geologic conditions,tidal current,and surrounding environment.Taking a public waterway project as an example and adopting tidal current and sediment mathematical model tests and ships maneuvering tests,we demonstrate on the plan layout of a channel from aspects including the natural conditions of the project area,the relationship between the project and the environmental protection zone,and the mid-long-term development planning of the port,and determine the optimal axis plan.We also discuss the design innovations when determining the channel dimensions to provide technical reference for the layout of similar long-distance channel projects with many comprehensive constraints.
