摘　　要：文章旨在评估刚柔复合式路面中水泥混凝土板接缝传荷能力的影响因素,以提高路面性能和延长使用寿命。通过有限元模拟,探究模量变化、沥青层厚度、弹性模量及厚度变对水泥混凝土板接缝传荷能力产生的影响。研究发现,适当调整这些参数能显著提升接缝的传荷效率。基于实验数据,提出了适用于刚柔复合式路面的接缝传荷性能控制指标,为路面检测和维护提供了新标准,有助于优化路面设计和施工,确保行车安全。The purpose of this paper is to evaluate the influencing factors of load transmission capacity of cement concrete slab joints in rigid-flexible composite pavement,so as to improve pavement performance and prolong service life.Throughfinite element simulation,the effects of modulus change,asphalt layer thickness,elastic modulus and thickness change on the load transmission capacity of cement concrete slab joints are investigated.Research has found that proper adjustment of these parameters can significantly improve the load transmission efficiency of joints.Based on the experimental data,the joint load transmission performance control index suitable for rigid-flexible composite pavement is proposed,which provides a new standard for pavement detection and maintenance,helps to optimize pavement design and construction,and ensures driving safety.
