Open publisher page 2 citations

Abstract

Based on a case of a highway embankment on collapsible loess ground,an impact compaction technology for collapsible loess ground is developed. During the process of compaction,the elastic modulus, compaction degree,collapsibility,settlement and other parameters of the soil are measured and the depth of impact compaction is comprehensively studied. The results of experiment indicate that the elastic modulus and compaction degree increase and the collapsibility and settlement decrease with impact compaction,and impact compaction is effective in improving the quality of embankment and reducing the settlement after construction.
