Numerical Analysis of the Settlement of Composite Foundation Reinforced with Crushed Stone Grouting Pile and Rigid Bearing Plate

This paper deals with a new type of crushed stone grouting pile with a rigid bearing plate.The load transfer characteristics were analyzed,and a settlement model of the composite foundation reinforced with crushed stone grouting pile and rigid bearing plate was built by FEM program.The effects of replacement ratio of capping plate,replacement ratio of pile,replacement ratio of grout diffusion zone,pilesoil modulus ratio,and seroussoil modulus ratio,on the composite foundation settlement were discussed.It is...
