自动化集装箱码头综合管沟结构设计

Structural design of utility tunnel for automated container terminal

综合管沟是近10 a来我国城市地下管线铺设的新型设计思路,在港口工程中的应用较为少见。港口工程具有独特的平面布置,场区内管线类型、地基条件、荷载、地面设施、交互节点等均与其他管沟大不相同,结构设计条件非常复杂。针对上述问题,在广州港南沙四期工程综合管沟结构设计中,结合自动化集装箱码头的特点,对荷载条件、沉降要求等方面进行了研究,提出了多功能盖板段、渐变式复合地基等方面的优化设计思路,完成了适用于自动化集装箱码头的综合管沟结构设计,有效解决了管线综合的问题。本文所阐述的结构设计经验对后续的自动化集装箱码头综合管沟结构设计具有一定的参考意义。

Utility tunnel is a new design idea for laying underground pipelines in cities in the past 10 years.However,its application in port engineering is relatively rare.The port project has a unique layout.The pipeline types,foundation conditions,loads,ground facilities,and interactive nodes in the site are very different from those of urban utility tunnel.The structural design conditions are very complex.In view of the above problems,in the utility tunnel design of Guangzhou Port Nansha Phase 4 Project,combined with the characteristics of the automated container terminal,the load conditions,settlement requirements and so onare studied.Then the optimization design ideas of multi-functional cover section and the gradient composite foundation are proposed.Through the above optimization design ideas,the utility tunnel structure design suitable for automated container terminals has been completed,which effectively solves the problem of pipeline integration.The structural design experience described in this paper has certain reference significance for the structural design of the utility tunnel of subsequent automated container terminals.
