水泥混凝土路面因使用寿命长,施工简便、养护工作量小等特点,在高等级路网结构中占据重要地位。但对于早年的水泥混凝土路面,因脱空、断裂等病害大大影响了使用寿命。如半刚性基层路面的雨水冲刷问题,刚性基层路面基层与面层在温度翘曲应力下的破坏等问题。本研究将围绕水泥混凝土路面结构,就冲刷和疲劳破坏等机理进行分析,为提出改进方法提供技术参考依据。 Due to its long service life, simple construction and small maintenance workload, cement concrete pavement occupies an important position in the high-grade road network structure. But for the early years of cement concrete pavement, due to the void, fracture and other diseases have greatly affected the service life. Such as the problem of rainwater scouring on the semi-rigid base pavement and the damage of the base and surface of the rigid base pavement under the temperature warping stress. This study will focus on the cement concrete pavement structure, erosion and fatigue failure mechanism analysis, to provide a method for improving the technical reference.
