摘要
根据界面断裂力学的有关概念和原理,将复合式路面视为界面断裂力学中的界面层模型,得到Cauchy奇异积分方程组,并运用Lobatto-chebyshev法解此方程组,求出未知的位错密度函数,从而得到裂纹尖端的应力强度因子,并由此计算出路面的极限承载力。
In this paper interfacial fracture mechanics is brought into the numeration of composite pavement. The composite pavement is looked as the mechanical modeling of the interfacial fracture mechanics. We obtain Cauchy singular integral equations. Which are solved by the Lobatto - chebyshev method commonly applied to such problems. then we obtain the unknown dislocation density functions,and the stress intensity factors near the crack tips,at last we can calculate the limit load.
