摘要
城市路网及轨道交通的逐步完善极大地提升了人民出行的幸福感,给城市经济发展也注入了强劲的动力,但有限的城市空间给桥梁结构设计带来了诸多挑战,安全性控制变得越来越艰难。以秀龙桥上跨地铁隧道工程为依托,详细说明了秀龙桥的设计原理,在满足现有规范的基础上,利用桥梁博士等软件计算,验证设计方案的可行性,确保桥梁结构安全。可为今后桥隧立体交叉工程设计提供借鉴和参考。
The gradual improvement of the urban road network has greatly improved the happiness of people’s travel and injected a strong impetus into the urban economic development.However,the limited urban space has brought many challenges to the bridge structure design,and safety control has become increasingly difficult.Based on the subway tunnel project over the Xiulong Bridge,this paper explains the design principle of Xiulong Bridge in detail.On the basis of satisfying the existing specifications,the feasibility of the design scheme is verified by software such as Doctor Bridge to ensure the safety of the bridge structure.It can provide reference and reference for future bridge-tunnel three-dimensional crossing engineering design.
