摘要
本文论述了半刚性基层上沥青面层开裂的力学机理和断裂力学的应用,通过实例计算表明,边界配置法在沥青面层反射缝分析中是一种计算裂缝端应力强度因子的简便实用的方法。
In this paper, the mechanical problem of bituminous pavement crack on semi-hgid rigid foundation is investigeted. The boundary collocation of fracture mechanics is used for calculation of the stress intensity factors of crack tip. The numerical results show that it is a simple and practical method for anal- ysing the reflection crack,of bituminous pavement.
