摘要
以水泥混凝土路面为研究对象,采用三维有限元方法分析了地基不均匀沉降条件下水泥混凝土板的应力变化,得出了板底弯拉应力、混凝土板的最大主拉应力与路基不均匀沉降之间的关系,探讨了水泥混凝土板在地基不均匀沉降地段的受力机理,为水泥路面设计提供参考。
Taking cement cincrete pavement structure as object of research, the 3-D finite element is used to analyze variation of stress upon pavement structure under load under differential settlement of foundation. The relationships between slab bottom flexural-tensile stress, concrete slab max, tensile stress and differential settlement of foundation are obtained, and the strain mechanism of cement concrete pavement of the differential settlement part, which provides reference to design of special segment road face structure.
