| 摘 要： | 连续配筋混凝土刚柔复合式沥青路面是一种新型复合式路面结构,具有强度高、整体性强等优点,但由于沥青与混凝土层间变形协调性能差,易发生剪切破坏。基于弹性层状体系理论,采用BISAR3.0程序计算了连续配筋混凝土刚柔复合式路面层间最大剪应力,研究分析了温度、结构层厚度、表面摩擦系数、轮载等主要影响因素对层间最大剪应力的影响,揭示了层间最大剪应力的分布规律。结果表明,层间最大剪应力随着温度、表面摩擦系数、轮载增加而增加,且变化幅度明显;随着结构层厚度的增加而减小,趋于非线性下降。

The Analysis of Interface Shear Stress in Rigid-flexible Composite Pavement with Continuously Reinforced Concrete |
| |
| Abstract: | Composite asphalt pavement of continuously reinforced concrete is a new composite pavement,which has the ability of high strength and well integrity.However,it is easy to have the shearing failure due to its bad coordination between AC and CRC cell.Based on the elastic layered system theory,a calculation program BISAR3.0 is used to study the maximum shearing stress,including temperature,layer thickness,surface friction coefficient,wheel load,etc.on the main factors effect.The calculation results showed that... |
