摘　　要：为深入分析水平荷载对路面结构的影响,以复合式基层沥青路面结构为例,考虑层间不完全连续接触条件,竖向荷载采用重载条件,采用壳牌设计软件BISAR3.0为计算工具,考查水平荷载对复合式基层沥青路面力学响应的影响。结果表明：在层间不连续条件下,水平荷载对结构弯拉应变与弯拉应力分布没有影响,水平荷载作用使结构剪应力骤增、剪应力分布产生较大变化。In order to deeply analyze the effect of horizontal load on pavement structure, this paper took compound base asphalt pavement as an example, considering interlayer binding condition of not totally continuous, and setting the vertical load as heavy load, then the effect which horizontal load acted on mechanical response of compound base asphalt pavement was analyzed by shell calculation soft Bisar3.0. The results showed that under the interlayer binding condition of not totally continuous, horizontal load had no effect on the structural distribution of flexible stress and flexible strain; horizontal load made shear stress of structure greatly increase as well as the distribution of shear stress change a lot.
