Shear Behavior of Mortar Layer in Continuous Slab Track with Different Arrangement Schemes of Embedded Steel Bars

  • 摘要: 为研究不同温度条件下的合理植筋方案,采用基于表面的内聚力模型模拟轨道板与砂浆层界面剪切破坏过程中层间黏结-脱黏-接触的复杂相互作用关系,考虑剪力筋的非线性约束特性,建立了纵连板式轨道三维有限元模型,并结合既有的推板试验结果对模型合理性进行验证,细致分析不同植筋方案下轨道板与砂浆层间的抗剪性能.研究结果表明:植筋可以明显提高轨道层间抗剪性能;层间开裂时对应的轨道温升幅度可由无植筋时的10.5℃提高到30℃;温升幅度小于20℃时,采用16+8+8植筋方案,温升幅度在20~30℃之间,采用16+16+16+10+8植筋方案,超过30℃时,需辅助其他限位措施.
