韩国跨坐式单轨交通预应力混凝土轨道梁设计评价

摘要

In this paper, the design of pre - stressed concrete (PSC) track beam in Korean straddle monorail transit is mainly introduced, including the cross section, beam span, concrete grade, pre-stressing design and common reinforcement design. Compared with the detailed indexes of PSC track beam design in Chongqing, the track beam design of Daegu subway Line 3 is evaluated, the design features, the advantages and the disadvantages of PSC track beam are summarized, some improved suggestions are put forward.%对韩国大邱跨坐式单轨交通预应力混凝土轨道梁设计进行了介绍,包括梁截面、跨度、梁体混凝土等级、预应力设计和普通钢筋设计.通过与重庆预应力混凝土轨道梁的各项设计进行详细对比后,对韩国大邱预应力混凝土轨道梁的设计进行了评价,并给出了改进建议.
