半刚性基层与刚性面层联结状态对刚性路面荷载应力的影响分析

Effect of Joint State of Interface in between Rigid Concrete Plate and Semi Rigid Base on Stress in Pavement

摘要: 本文应用空间有限元理论，模拟半刚性基层与刚性路面层间联结状态，提出层间联结剪切损伤变量。应用空间有限元理论与弹性半空间体解析解相结合的方法，将半刚性基层刚性路面视为弹性半空间地基上的双层弹性体，分析半刚性基层与刚性面层层间联结状态对荷载应力的影响。计算结果表明层间联结状态对荷载应力有十分显著的影响

Abstract: In this papaer, the contact condition on interface between rigid concrete plate and semi rigid base is simulated by three dimensional finite element method Shearing damage variable for interface is put up The results proved that the contact state in the interface has notable effect on stress in pavement
