肋拱桥加固设计的力学分析研究

针对目前工程中采用较多的肋拱桥原设计荷载标准难以满足日益增长的交通量的需要,在使用中出现病害,需要进行提载加固的问题,提出了提载加固的力学分析模型,并以实例的形式对提出的计算模型进行分析研究。

Mechanical Analysis and Study on Reinforcement Design of Rib Arched Bridge

Aiming at the original design load standard of rib arched bridge more used in the present projects hard to satisfy the increasingly increasing demand of traffic volume, the article analyzes the faults in the use to require the loading reinforcement problems, and puts forward the mechanical analysis model of loading reinforcement, and analyzes and studies the this model by the practical cases.
