水平荷载对沥青路面结构的影响
Influence of horizontal loads on asphalt pavement structure
【摘要】 轮胎与路面间的接触压力具有很明显的非均布特性,不同于传统的双圆均布垂直荷载。根据轮胎胎面花纹类型,并参考接触压力的测试结果,提出车轮对路面作用的荷载简化模型。通过计算分析,得到不同水平荷载大小和荷载分布形式下路面结构内的剪应力变化情况。结果表明,水平荷载的大小对路面10cm内的影响较大。
【Abstract】 The interfacial pressure between tire and the pavement exhibits a highly non-uniform distribution over the contact area, which is different from the circular uniform vertical pressure traditionally used for pavement analysis.On the basis of abundant literature, a simplified load model was put forward according to the tire tread patterns.The response of the pavement under different load magnitudes and load patterns was obtained through finite element method. The results show that the horizontal loads have a big influence on pavement structure within 10 cm.
