摘要
基于路基纵向裂缝的特点和处治难度,利用土工格栅和级配碎石各自的优良性能,提出了柔性枕梁处治技术。通过有限元分析,研究了不同荷载位置、裂缝宽度、路基侧向滑移和不均匀变形等4种情况下,处治路基结构的受力特点;进而对柔性枕梁处治结构的各设计参数,如柔性枕梁的模量、厚度、宽度及调整层厚度等,进行了力学分析,推荐了合理的使用范围。
Due to the characteristics and difficulties of subgrade longitudinal cracks, a flexible beam (FB) technique is put forward. Through the FEM analysis, the strength laws of pavements under different loading sites, crack widths, side slippage and asymmetry deformation are studied; in addition, the design parameters including modulus, thickness, width and adjusting layer of the FB are analyzed, and the useable range of each parameter are also recommended.
