Time-Domain Analysis of Tamper Displacement during Dynamic Compaction Based on Automatic Control

Crater depth is a vital issue in dynamic compaction (DC) because it controlling parameter DC and characterization index of soil properties. A continuous mathematical model capturing the time-domain process tamper displacement presented this paper. The simple parameters involved are easy to obtain. It was found that accumulated crater increases but its increment decreases with multiple impacts. Three groups large-scale tests 10,000 kN?m were conducted evaluate performance proposed model. results showed captures typical trends single In addition, concept ratio based on model, used efficiency predict optimum tamping number DCs.
