Abstract: In loess foundation engineering, it is often necessary both to eliminate the collapsibility and increase the bearing capacity. down hole deep compaction is a relative new foundation treatment method. The analysis of tests results, including in-situ single piles loading tests, loading tests on soils between piles and other tests, illustrates that the down hole deep compaction is an effective foundation treatment method to eliminate the collapsibility of loess, increase the bearing capacity and improve the behavior of composite foundations.

Key words: down hole deep compaction, loess, collapsibility, bearing capacity
