路面面层内反射裂缝强度因子的数值分析

Numerical Analysis of Stress Intensity Factor of Asphalt Pavement Reflect Crack

应用有限元软件ANSYS,建立路面结构模型,对裂缝在面层内的应力强度因子进行数值计算,分析路面材料性能对拉开型开裂强度因子和剪切滑动性开裂强度因子的影响,以及这两种强度因子在裂缝扩展过程中的变化规律。

Using the finite element software ANSYS,this paper establishes the road model,to calculate stress intensity factor of the cracks in the surface layer,to analyze the material properties impacted on the KI、KII and its law of the cracks expansion process.
