摘要
在分析水泥混凝土路面接缝错台产生机理的基础上，对国外八大横向接缝错台预估模型进行对比研究，结果表明：接缝错台变化随着时间的推移增幅逐渐减小，最后趋于平缓；板底支承变形能量、基层和路基的侵蚀指数以及自由水指数是所有模型均考虑的影响因素；设传力杆能显著减小接缝错台量；路肩类型也是影响接缝错台变化的重要因素，最后给出了对应的降低接缝错台量的措施。
Based on the mechanism analysis of joint faulting in cement concrete pavement, the eight foreign prediction models of joint faulting are comparatively studied. The results show that the growth rate of joint faulting decreases to being flattening as the time going on;the bottom bearing deformation energy, the erosion index of base and subgrade, and the free water index are the influence factors of all models;the dowel bar could significantly reduce the joint faulting;shoulder type is also an important factor that affect joint changes. The corresponding measures to reduce the joint faulting are finally purposed in the paper.
