Research of Deformation Characteristics of Long-Short Pile Composite Foundation under Rigid Foundation

Abstract:

Long-short composite pile is a widely used ground improvement technique. This study presents the results of finite difference analyzes using FLAC3D software to investigate the deformation behavior of long-short pile composite foundation under rigid foundation. The pile penetration into cushion and displacement distribution in the piles and other parameters are also studied. The results show that settlement is much more significantly affected by long-pile rather than short-pile. On the other hand, long-pile pierce into cushion to bring foundation soil into full play, also makes the advantages of long-short pile composite foundation to be evident.
