摘要
结合哈尔滨市二环路部分预应力结构工程实际,通过与常规设计板梁梁结构技术经济指标的综合分析比较发现,部分预应力结构具有技术经济指标先进、节省主要材料用量等特点,是大批量应用于中小跨径桥梁之首选结构形式,是桥梁设计、建造标准化的发展方向。
Combining with portion prestress structure engineering practice of Harbin city, comparing with normal plate girder structure, this paper points out that portion prestress structure is of the advantages of advanced technical and economic indices, saving materials so it is widely used in bridge with middle and small span.
