太原市南中环快速路高架桥箱梁计算分析

摘要

Software Doctor Bridge is used to establish a model of(36+56+36)m continuous box girder,which is on South-middle-circle road in Taiyuan city after construction to be finished. Different working conditions are considered to calculate mechanical properties of the bridge on per-manent load or permanent and variable load,including longitudinal and transverse calculation of superstructure. Calculation results indicate that the maximal tensile and compression stress of the bridge section can meet requirements in design specification for normal use.%以已施工完成的太原市南中环快速路高架桥（36＋56＋36）m连续箱梁为例，采用有限元软件桥梁博士建立其计算模型，按不同工况计算该桥在恒载和恒载＋活载作用下的桥梁力学性能，包括上部结构纵向和横向计算分析，计算结果表明，桥梁截面拉应力和压应力均可满足规范要求。
