着重从力学分析角度阐述了水泥混凝土路面早期损坏的原因,并分析了排水系统和施工质量的影响,系统地完善了水泥混凝土路面的设计施工过程。力学分析建议增加最重轴载验算,避免板面产生极限断裂;并掌握模量、弯拉强度同龄期的增长关系,尽量避免提早开放交通。横向接缝下采用透水性上基层,并铺设防水材料,辅以边缘排水系统是解决唧泥、错台的有效方法。
The reasons for the early damage of cement concrete pavement are expounded from the perspective of mechanical analysis. The influence of drainage system and construction quality is analyzed, and the design and construction process of cement concrete pavement is systematically improved. Mechanical analysis suggests adding the heaviest axle load checking to avoid the limit fracture of the plate; and grasping the growth of modulus and bending strength at the same age, try to avoid early opening of traffic. Under the horizontal seams, the water-permeable top layer is used, and the waterproof material is laid together with the edge drainage system, which is an effective method for solving the problems of pumice mud and muddy mud.
