An Analysis on Failure Pattern of CFG Pile-Net Composite Foundation of High-Speed Railway
Advanced Materials Research, 2012CFG pile-net composite foundation has the advantages of small post construction settlement and uneven settlement, easy control of construction quality and fast construction speed. It`s widely used in subgrade engineering of high-speed railway. However, in coastal soft soil area, phenomena like breaking pile, collapsed embankment, cracking in embankment

Three-dimensional nonlinear finite element modeling of composite foundation formed by CFG–lime piles
Computers and Geotechnics, 2008Abstract Cement–Flyash–Gravel (CFG) pile is a widely used ground improvement technique. A CFG–lime multi-pile composite foundation is a new concept utilizing CFG and lime piles. This study presents the results of finite element analyzes using ANSYS software to investigate the behavior of composite CFG–lime pile foundations under various load ...
