摘要
运用有限元法,对交通荷载作用下CRC-AC复合式路面AC层的应力状态进行研究。研究表明,由于路表存在横向、纵向拉应力,在长期交通荷载作用下,AC层表面有可能产生横向、纵向开裂;并分析路面结构参数对AC层横向最大拉应力的影响,提出相应建议。
The author made a research on the stress of AC layer of CRC-AC composite pavement under the traffic load with finite element method. AC layer would probably appear transverse and vertical cracks because of transverse and vertical tensile stress in pavement under the long-term traffic load. The author analysed the influence of pavement structure parameter on the max transverse tensile stress of AC layer, then applied related advice.
