摘　　要：半刚性沥青路面在我国高速公路路面中应用广泛,但由于沥青面层与半刚性基层的层间变形协调性差,易产生较大的层间剪应力而引起沥青面层的剪切破坏。文章基于弹性层状体系理论,采用BISAR3.0软件分析了材料回弹模量、泊松比、行车荷载、层间结合状态等因素对沥青面层和半刚性基层层间最大剪应力、压应力的影响,并总结出各因素影响下的应力分布规律。Semi-rigid concrete is widely used in national highway pavement.But because of its low deformation capacity,the concrete pavement is easy to break by shearing strength.Based on elastic multilayer theory,the article uses the BiSAR 3.0 software to analyze the influence of modulus of resilience,poisson＇s ratio,and vehicle load and layers joint conditions on shearing strength of concrete pavement and semi-rigid layers.It summarizes the stress distribution under each factor in the end.
