Research on FLAC 3D Numerical Simulation of Working Mechanism of Compaction Pile Composite Foundation

Abstract:

Compaction piles is one of the conventional methods for foundation treatment in collapsible loess, there are very few research results about soil compaction effect between piles when forming the piles. Firstly, the stress field and displacement field of soil around compaction piles are elastic-plastic analyzed on the basis of the cavity expansion theory; then a series of FLAC 3D numerical simulations were performed to evaluate the treatment effect of the compaction pile composite foundation. The result shows that all bearing capacity has improved, and quicklime compaction pile composite foundation has been increased remarkably. It embodies the correctness of the computation theory. And the feasibility of the compaction piles composite foundation on collapsible loess area is further proved.
