Research on Soil Bearing Characteristics and Pavement Structure Mechanical Response Based on Subgrade Improvement Design
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.
