摘要: 针对高等级公路软土地基不均匀沉降问题.本文提出了地基不均匀沉降对路面结构产生附加应力的分析模型,并采用平面八节点等参元法分析了不同沉降值对路面响应的影响.最后本文提出了软土地基不均匀沉降指标容许值,供生产实践进一步研究时参考.

关键词: 软土地基, 不均匀沉降, 等参有限元法

Abstract: In this paper,about highway pavement on soft soil foundation differential settlements problem, the aditional stressanalysis model is presented on differential settlements to pavcment structure.Using 8-point equation parameter finite elemints mothod,the affection is analysed about differential settlements value to pavement structure. Finany,the differentialsettlements index value is produced and is for deeping study reference.

Key words: soft soil foundation, differential settlements, equation parameter FEM
