从水泥混凝土路面动水作用试验研究分析,文章分析了水泥混凝土路面面层对基层影响导致的三种基本破坏形式;通过断裂力学的基本原理可以揭示水压力对水泥混凝土面板的劈裂作用机理,结合基层冲刷试验,提出了水对混凝土路面的影响不可忽视,也是设计、施工、养护部门共同面对的技术问题。有必要对水泥混凝土路面与基层之间设置隔离层,设置隔离层的水泥混凝土路面结构可以在一定程度上减小水对水泥混凝土路面的影响。
Based on the experimental study and analysis of dynamic water effect on cement concrete pavement, the paper analyzes three basic failure modes caused by cement concrete pavement impact on the grassroots. Based on the basic principles of fracture mechanics, the mechanism of water splitting on concrete slab can be revealed. Combined with the erosion test, it is put forward that the influence of water on the concrete pavement can not be neglected, and is also a technical problem that the design, construction and maintenance departments face together. It is necessary to set up an isolation layer between the cement concrete pavement and the grassroots. The cement concrete pavement structure with the isolation layer can reduce the impact of water on the cement concrete pavement to a certain extent.
