本文首先说明采用装配式钢筋混凝土桥梁的必要性,再从介绍苏联在这方面的成就和经验指出我国在推广装配式钢筋混凝土铁路桥梁中所要解决的问题。本文是根据苏联最近出版的一些文献写成的,可能不够全面。为了便于读者较深入地去研究起见,文中广泛地注出资料的来源。Ⅰ.推广装配式钢筋混凝土桥的必要性。采用钢筋混凝土结构可以节省钢料,图1示各种桥跨所用钢料的重量及混凝土体 This paper first explains the necessity of using fabricated reinforced concrete bridges, and then introduces the achievements and experiences of the Soviet Union in this regard and points out the problems to be solved in our country in popularizing prefabricated reinforced concrete railway bridges. This article was written based on recent literature published by the Soviet Union and may not be comprehensive enough. In order to facilitate readers to more in-depth study, the article out of a wide range of sources of information. I. The Necessity of Popularizing Assembled Reinforced Concrete Bridge. The use of reinforced concrete structure can save steel, Figure 1 shows a variety of bridge span steel used in the weight and concrete
