摘要
基于弹性薄板有限元理论,本文较全面地分析了刚性路面设计中两种地基模型刚度指标的关系,得到了一系列E_s-K换算关系式,对两种地基模型的合理性进行了综合评述,利用E_s-K关系式和已有的试验验证资料,提出了采用E地基时确定几种临界荷位情况下地基计算回弹模量的实用公式。
In this paper,the relationships of rigidity indexes of two foundation mod-els under rigid pavements are studied based on the finite element analysis of slabs on e-lastic foundation , and a set of E_s-K conversion formulas are presented. The practica-bleness of two foundation models is commented. The practcalformulas used to deter-mine the revised modulus of resilience of foundation on variouscritical loading positionsare developed on the basis of existing experimental results
