摘要
针对汕头湾海底隧道地质构造复杂、海水压力等级高、施工工法类型多、超大直径盾构等难点,在对汕头湾海底隧道进行BIM设计的基础上,重点从盾构隧道管片参数化排布、管片钢筋精细化设计、海域段三层衬砌防排水系统精细化设计、拆解洞精细化设计及施工仿真、风化深槽破碎断层带海面垂直注浆加固设计、盾构管片健康监测布线方案比选6个方面开展了BIM专项应用,解决了设计优化、方案比选和关键技术创新等问题,实现参数化、精细化、可视化的设计施工一体化应用。可为类似工程BIM研究及深化应用提供参考。
In view of the difficulties such as complex geological structure,high seawater pressure level,various types of construction methods and super-large diameter shield of Shantou Bay Undersea Tunnel,on the basis of BIM design for the whole Shantou Bay Undersea Tunnel,special BIM applications are carried out from six aspects:parametric arrangement of shield tunnel segments,refined design of segment reinforcement,refined design of three-layer lining waterproofing and drainage system in sea areas,fine design and construction simulation of tunnel disassembly,vertical grouting reinforcement design on the sea surface of fracture fault zone of weathered deep groove,and comparison and selection of shield segment health monitoring wiring schemes.It solves the problems of design optimization,scheme comparison and selection and key technology innovation,and realizes the integrated design and construction of parametric,refined and visualized application.It can provide references for BIM research and further application in similar projects.
