沉管受限水域浮运航道设计*

结合现有项目工程的航道使用条件,依据国内外调研成果及爯内河通航标准爲爯海港总平面设计规范爲,对有限水域内大型沉管的浮运航道进行设计,得出航道设计的宽度与深度等关键技术参数,并在港珠澳大桥沉管隧道沉管浮运航道的选择中得到应用,通过对沉管在现场实测应用中分析计算,得出沉管浮运的航迹线.分析及研究成果经过实际应用验证,满足工程施工的要求.

Design of immersed tube floating channel in limited water area

Combining channel service conditions of the existing project,according to the achievements of investigation and research in native and foreign,Inland river navigation specification,Code for design of general layout of sea ports,we design the floating channel in the limited water area and large immersed tube,obtain the key technical parameters of the width and depth of the channel design,and apply the technique in selection of floating channel of the Hong Kong-Zhuhai-Macao Bridge immersed tube tunnel.According to measurement and analysis of the immersed in the project,we obtain the track line of the immersed floating.The analysis and results are verified by practical application,and satisfy the engineering construction requirements.
