分析了剪力齿槽的作用机理,认为剪力齿槽是传递底座板纵向力和限制底座板位移的重要结构,是无砟轨道结构系统和桥梁相互作用的纽带。介绍了剪力齿槽的结构设计和受力分析,针对施工中常见的质量缺陷,对可能造成的影响进行了定性分析,并对处理方案提出了相关建议,旨在引起相关建设者的重视。 The mechanism of shear gullet is analyzed. It is considered that the shear gullet is an important structure that transmits the longitudinal force of the base plate and limits the displacement of the base plate. It is also the link between the ballastless track structural system and the bridge. The structure design and stress analysis of shear tooth slot are introduced. According to the common quality defects in construction, the possible influence is analyzed qualitatively, and some suggestions are put forward to deal with the solution, aiming to arouse the attention of relevant builders.
