山区河流码头船舶靠离泊模拟仿真技术研究与应用

摘要

针对山区河流码头船舶靠离泊为低速、大回旋运动过程的特点,采用尺度效应修正的方法对小比尺船模进行操纵相似性率定,并在金沙江中嘴码头水工模型上进行仿真模拟试验.结果表明,小比尺船模模拟技术用于山区河流码头船舶靠离泊仿真是实用有效的,可为相关工程设计提供有价值的依据.%According to the characteristics of low speed and large cyclotron motion for ship's berthing and unberthing in mountainous rivers wharf,we adopt the scale effect correction method to calibrate the manoeuvre similarity of small-scale ship model,and conduct the simulation experiment on the hydraulic model of Jinshajiang River middle mouth pier.Test results show that it is practical and effective to use the small-scale ship model technology for the simulation of ship's berthing and unberthing in mountainous rivers wharf,and may provide valuable basis for the related engineering design.
