Analysis of Bearing Capacity for Quicklime Compaction Pile Composite Foundation

In the collapsible loess of Midwest China, quicklime compaction pile composite foundation has been widely used in practical engineering. Firstly，the calculation method of quicklime compaction pile composite foundation is analyzed; then the influencing factors of bearing capacity for quicklime compaction pile composite foundation was researched on the basis of the character about soil compaction effect between piles with the quicklime expanding when absorbing water from the soil; lastly, the calculation method was used in practical engineering, the results can be used to reference in reliability design application of composite foundation.
