Abstract: We have some construction about 3000－15000kN m energy dynamic compaction for collapsible loess. Through comprehensively analying the results of standard penetration test, soil mechanics experiment, cone penetration test, Rayleigh test, static test, and comparing with other energy dynamic compaction result of collapsible loess, some outcomes of effective reinforced depth and coefficient of collapsibility are obtained. Finally, an empirical equation for dynamic compaction of this area is proposed; and it can be for reference in design, construction and detection of collapsible loess

Key words: collapsible loess, foundation treatment, dynamic compaction, detection
