Aiming at backfilled foundation,formulas of reinforcement depth and cumulative settlement have been obtained by dimensional analysis.The proposed formulas have been validated combined with the existing engineering data.The results show that the formulas can more accurately predict reinforcement depth of backfilled foundation and cumulative settlement,and also can analyze the relationship between cumulative settlement and reinforcement depth.The results showed that the ratio of cumulative settlement and reinforcement depth varies with many factors, and only in certain distance and rammer radius,can it be extended as a constant.In the last,we analyze the impact of the hammer radius and thickness on the effect of dynamic compaction.The conclusion has a certain reference value for similar practice.
