摘要
为研究路基改良设计下路基土体承载力学及水泥混凝土路面结构层力学响应特征,文章采用了力学试验及动力响应计算方法,分析了改良剂掺量和改良深度对路基、路面结构层的影响.研究表明,围压作用对改良土试样应变的影响效应大于改良剂掺量,需着重考虑围压作用对应变的影响.
Abstract
In order to study the bearing mechanics of subgrade soil and the mechanical response characteristics of cement concrete pavement structure layer under subgrade improvement design,the mechanical test and dynamic response calculation method are used to analyze the influence of modifier content and improvement depth on subgrade and pavement structure layer.The research indicates that the influence of confining pressure on the strain of the improved soil sample is greater than that of the modifier content,and the influence of confining pressure on the strain needs to be considered.
