-
摘要: 本文提出一种可用于分析软土地基不均匀沉降所引起的铺面结构层内附加应力的计算方法。分析结果表明,可通过合理选用铺面结构层次的组合及其刚度,调整附加应力;在软土地基上采用夹层结构,对于降低附加应力、方便施工有较好的效果。Abstract: A new analytical method has been developed for calculating the bending stresses in concrete pavements due to differential settlements of subsoils. It has been shown that the induced stresses could be lowered by increasing the relative stiffness of the slab or the whole pavement structure, by shortening the slab length, and by using the "sandwich" layer structure.
