摘　　要：针对拖轮拖带沉管浮运航道宽度的既有设计方法具有局限性的问题,基于数值仿真进行了浮运航道宽度设计的研究。采用数值仿真模拟结果计算的深中通道沉管浮运航道宽度随拖轮就位时间增加而增加、随纠偏力增大而变小,较参考《海港总体设计规范》计算数值小约17 m。基于数值仿真的浮运航道宽度设计方法考虑了拖轮协同操纵因素,丰富了拖轮拖带沉管浮运航道宽度设计的方法,可为类似工程提供借鉴。The existing design method for the channel width of immersed tube floating by tug towing has limitations.In response to this problem,a study is carried out on the floating channel width design based on numerical simulation.The floating channel width of the Shenzhen-Zhongshan Bridge gained from numerical simulation results grows with the time of tugs being in place,while decreases as the rectifying force increases.It is about 17 m smaller than the value calculated depending on the Design Code of General Layout for Sea Port.The design method of floating channel width based on numerical simulation takes into account the cooperative maneuver of tugs,enriches the width design method for immersed tube floating,and can provide a reference for similar projects.
