摘要
运用大型通用有限元软件ANSYS对水泥混凝土路面面层和基层贫混凝土的层间作用进行了分析,结果表明:水泥混凝土路面面层和基层贫混凝土之间的综合摩擦系数fn的最大取值不应该超过9.0。把室内水泥混凝土与贫混凝土界面的直剪试验结果和有限元计算数据对比分析,可以得到不用层间处理状况下所对应的水泥混凝土面层与贫混凝土基层之间的结合系数ku。
In this article,the general finite element software ANSYS is used to simulate the interfacial interaction between concrete pavement and lean concrete base, and the conclusion indicates that the value of interfacial skid resistance coefficient fn should not pass 9.0. Contrasting direct-shear-test results between concrete pavement and lean concrete and finite element estimated dates, the coupling coefficients k are obtained by different processing condition between concrete pavement and lean concrete base.
