接缝是水泥混凝土路面结构最薄弱的部位,其传荷能力直接影响路面结构设计和使用性能。通过广泛的资料调研和分析,在回顾有关水泥混凝土路面结构力学响应研究的基础上,对接缝传荷作用的模拟、接缝剪切刚度的确定和接缝传荷能力的评价等内容的研究现状进行了系统总结。最后指出有关接缝传荷能力研究中存在的问题和发展趋势,提出应重点考虑接缝传荷与板底脱空的耦合作用和分离方法。
Seams are the weakest parts of cement concrete pavement structure, and its transmission capacity directly affects the pavement structure design and service performance. Through extensive data research and analysis, based on the review of the study on mechanical response of cement concrete pavement structure, the simulation of joint load transfer, the determination of joint shear stiffness and the evaluation of joint load transfer capability The status of a systematic summary. At last, it points out the problems and development trend in the study of joint load transfer capacity, and puts forward that the coupling action and separation method of joint load transfer and board voidage should be considered.
