摘　　要：利用弹性层状体系理论,对多孔混凝土基层荷载应力进行数值分析,建立了荷载应力的回归模型,得到了回归模型的各项系数,结果表明回归系数均能通过检验,由此得到的多孔混凝土基层荷载应力计算公式精度好,表达形式简单,使用方便,可满足工程设计和理论研究的需要;最后分别采用刚性路面规范设计公式和回归公式2种方法对荷载应力进行计算,结果显示前者的计算值偏于保守。Using multi-layer elastic system,this paper analyzes the loading stress of porous concrete by numerical method,and establishs a regression model of the loading stress,obtains all kinds of coefficient of the model.The formulary of the loading stress is simple in expression,convenient in using and good at precision,it can be used for engineer design and theory research.Finnaly the loading stress is calculated by the ways of criterion formulary of rigid road and regression formulary,the results show that the former is conservative.
