摘要

半刚性基层沥青路面反射裂缝产生的原因之一是由半刚性基层温度变化引起的。根据路表代表性温度特征，运用有限元平面模型计算了裂缝尖端的应力强度因子，并对影响其大小的各因素进行了敏感性分析。结果表明，面层和基层的模量以及基层的温缩系数的增大会不同程度地导致裂缝尖端应力强度因子的增大，而面层的温缩系数对裂缝尖端应力强度因子的影响并不明显。另外，增加面层厚度能有效地降低裂缝尖端应力强度因子，并提出碎石基层可有效地减缓路面反射裂缝的扩展的结论。

Abstract

Temperature change of the semi-rigid base course is one of the reasons of appearance of the reflective crack. The stress intensity factor of the semi-rigid asphalt pavement is calculated with finite element method. Sensibility analysis is made on the parameters (modulus

thermal expansion coefficient

thickness) affecting the magnitude of the stress intensity factor. Finally

a conclusion that the graded gravel can reduce the reflective cracking

is drawn.
