Open publisher page 0 citations

Abstract

Combined with actual projects,the construction principle and dynamic compaction plan for subgrade in collapsible area were expounded,and the construction technique was introduced.In terms of the comparison of construction effect,a conclusion was drawn that the dynamic compaction reinforces the subgrade with an effect affected by the depth.The dynamic compaction can be a reliable measure for subgrade reinforcement in collapsible loess area.
