摘要
在传统水泥混凝土路面设计理论的基础上,引入断裂力学原理和方法,基于水泥混凝土路面"过渡层"的全新概念,分析水泥混凝土路面破坏过程,提出了设置隔离层的水泥混凝土路面新结构的设计理论,以达到提高路面实际承载力、延长路面实际使用寿命的目的。
Based on the traditional cement concrete pavement design theory, combining the theory and method of fracture mechanics, considering the new concept “transition layer” about cement concrete pavement, the paper analyzed the destroy process of cement concrete pavement and brought forward the design theory of cement concrete pavement with isolated layer to achieve the purpose increasing the bearing capacity of pavement and prolonging the pavement life.
