装配式混凝土结构综合管廊桥设计

Design of Fabricated Concrete Structural Utility Tunnel Bridge

基于某工程实例,提出了装配式混凝土综合管廊桥的结构形式。针对其受力特点并考虑施工要求,在综合管廊的基础上进行了断面调整,衍生出此次综合管廊桥设计断面。从有限元实体单元分析出发,着重研究了装配式混凝土综合管廊桥的屈曲稳定及受力性能,并进行了结构的纵横向计算。结合该工程给出了一些设计建议,研究结论和建议可为类似工程的设计提供参考。

Based on an engineering case,the structural style of fabricated concrete utility tunnel bridge is put forward.Aiming at its stress characteristics and considering the construction requirements,the section is adjusted on the basis of utility tunnel and the design section of this utility tunnel bridge is derived.Starting from the solid element analysis of finite element,the buckling stability and mechanical properties of fabricated concrete utility tunnel bridge are specially studied,and the vertical and horizontal calculations of the structure are carried out.Combined with this project,some design suggestions are given.The study conclusion and suggestions can provide the reference for the design of the similar projects.
