Computer Modeling for Different Piles Reinforcement in Control Deformation of Pavement

Abstract:

Multi-pile composite foundation is a method of ground improvement that involves using different pile types with different lengths and diameters beneath the same raft. The types of piles are chosen to mobilize the strength and stiffness of the soil at shallow depths. CFG (cement–flyash–gravel) pile and powder spraying pile have been widely applied in civil engineering, and gradually in highway foundation engineering. But the settlement of the pavement reinforced by the two types of piles has seldom been studied. In the present paper, the numerical simulation software FLAC3D is adopted to simulated the highway foundation reinforced by CFG pile and powder spraying pile , the spacing of piles and cushion thickness are changed, the settlements of the pavement are obtained to give guidance for the real practice.
