摘　　要：为解决综合交通枢纽市政道路桥梁、隧道与车站一体化设计中特殊建筑设计、特种结构选型与设计、集约利用城市空间资源等多方面难题,依托深圳市黄木岗交通枢纽工程,通过工程类比、模拟计算、现场验证等方法,对桥、隧、站一体化设计中重要节点进行方案比选研究。主要研究结论如下:1)群柱转换梁方案在站桥一体化结构转换中梁、板、柱尺寸适中,对室内建筑空间效果适应性较好,对承台与柱网不能对应的情况也有较好的适用性;2)车行隧道可丰富车站室内空间、对蓄烟仓划分起到积极作用,预应力吊墙技术对隧站一体化结构有很好的适应性;3)施工过程中,V柱与临时支撑的受力转换过程采用轴力伺服系统及“分批转换、同步加载、持续监测、严控变形”的原则可有效保障受力转换的均衡性;4)实践了地下建筑中结构与美学的统一。Special building design,special structure selection and design,and intensive utilization of urban spatial resources are critical in the integrated design of municipal roads,bridges,tunnels,and stations in comprehensive transportation hubs.A case study is conducted on the Huangmugang transportation hub in Shenzhen,China,using engineering analogy,simulation computation,and on-site verification approaches to compare the primary nodes in the integrated design of bridges,tunnels,and stations.The main findings are as follows:(1)The dimensions of the beam,slab,and column in the group column conversion beam scheme are appropriately sized for the integrated structural conversion of stations and bridges,exhibiting effective adaptability to the effects of the indoor building space and addressing the issue of abutment not aligning with the column grid.(2)The integration of tunnels and in-station space positively enriches the indoor space of the station and the partition of the smoke storage compartments.The prestressed suspended wall technology aligns well with the integrated structure of tunnels and stations.(3)The balance of force conversion can be effectively ensured during the construction process using the axial force servo system in the force conversion process between the V-column and the temporary support based on the principles of"batchwise conversion,synchronous loading,continuous monitoring,and strict deformation control".(4)The structure and esthetics of underground buildings have been united.
