板式无砟轨道结构锚固销钉限位技术可作为单元板式或纵连板式轨道结构的维修预案。针对提出的两种销钉设计方案,分别进行了单个销钉静态承载力、疲劳承载力以及实尺模型销钉承载能力的试验。试验结果表明,目前所设计的销钉布置方式,即采用4根间距在1 360 mm以上、直径40 mm的销钉方案应力幅值较小且受力均匀,可满足设计要求。 Slab ballastless track anchor bolt limit technology can be used as a unit plate or vertical plate track structure maintenance plan. According to the proposed two kinds of pin design schemes, the static bearing capacity, the fatigue bearing capacity and the bearing capacity of the dowel pins of a single pin were tested respectively. The test results show that the pin layout of the current design, that is, the use of four pins spaced more than 1 360 mm, diameter 40 mm pin stress less stress and force uniform to meet the design requirements.
