摘要:Foamed Cement Banking filling technology is one of the most effective methods in soft foundation treatments, such as the bumping at joints of a bridge-road, the different settlement of subgrade broadening and the stability problem of a high-filling embankment. To study on the characteristics of stress and strain for air-foam-treated lightweight soil, specimens were prepared at an optimized mixing ratio, and triaxial tests were conducted for strain and stress fitting. An ideal elastic-plastic model was used to simplify the relationship of strain and stress in an engineering sense, plus numerical simulation. The research results have great significance for addressing the issues of the stress-strain relationship, selecting design parameters and guiding engineering application with respect to air-foam-treated lightweight soil.
