中文摘要：

装配式T形截面混凝土多梁桥是我国公路桥梁建设中广泛应用。近年来有关其开裂、易损甚至倒塌事故不断出现。针对装配式梁桥的整体受力问题，研究横隔板的设置对荷载横向分布的影响。制作了缩尺模型，比较跨中、端部横隔板的影响差异。对比了横隔板设置数量对于横向分布的影响。并对传统手算方法、有限元模型进行验证。相关结果可为同类桥梁结构的设计提供参考。

Precast concreteand damage have appearedbridge ; effect of diaphragmmodel is madeof diaphragmselement （FE） T-Shape section beam bridges are constructed widely in China. In recently, crackcommonly for such kinds of bridges. This study focuses on integral stress of precastsetting on load transverse distribution is discussed based on the model test. Scaledto compare the different effect of immediate diaphragm and end diaphragm; effect of the amounton the transverse distribution. Furthermore, traditional manual calculation method and finitemethod are verified. The correlative results can be referenced for the design of similar bridge andstructure.
