Abstract:
According to the comprehensive testing data of 8 000, 12 000 kN·m high energy level dynamic compaction dealing with large-scale foundation, combining with indoor laboratory test data and the characteristics of loess region, the conclusions were obtained due to the effective reinforcement depth and the effect of dealing with collapsible loess. The factors impacting reinforcement effect, reinforcement depth of dealing with collapsible loess and the effect of dealing with foundation were analyzed. The results show that the systematic and comprehensive study of high energy level provides the basis for further analysis of the mechanism of dynamic consolidation particularly in collapsible loess region, meanwhile, it can provide optimized data for the design,construction and testing of dynamic compaction in the large-area.
