从详细的研究与发展规划的工作中提出了关于混混土箱形梁桥设计的各方面的资料。首先,对以往设计所作的综合分析使我们能够对结构的几何特性获得明确的概念,从而有利于对结构形状和尺寸的初步选择。其次,对有关的分析方法进行了考察,从而提出了它们在不同情况下的适用范围。此外,进行了翘曲应力和横向挠曲应力与纵向挠曲应力相比较的参数分析。最后,讨论了这些结构的极限强度。
From the detailed research and development planning work on the mixed-type box girder bridge design in all aspects of information. First, a comprehensive analysis of past designs allows us to obtain a clear idea of the geometry of the structure, which facilitates the initial selection of the shape and size of the structure. Secondly, the relevant analytical methods were investigated, and their applicable scope in different situations was put forward. In addition, parametric analysis of warpage stress and transverse flexural stress versus longitudinal flexural stress was performed. Finally, the ultimate strength of these structures is discussed.
