A 20,000 kN·m ultra-high-energy dynamic compaction trial will soon be implemented in Yan'an. Such a high treatment energy level is the first of its kind in China, and it will be an important strategic component for expanding development space in the construction of new urbanization.


        High-energy dynamic compaction can treat deep foundation soil in a single pass, effectively improve the compressibility of backfill and original ground, eliminate collapsibility, reduce fill layering, reduce the impact of cross-operation in earthwork, significantly shorten the time from site formation to stable post-construction settlement and delivery for use, shorten the construction period, and save investment. Therefore, ultra-high-energy dynamic compaction has great advantages in treating deep collapsible loess foundations.
