New Model and Its Validation for Calculating Limiting Bearing Capacity of CFG Pile Composite Foundation

This article analyses vertical bearing character of CFG pile composite foundation, according to the particularity of equal settlement surface, two shear failure model about CFG pile composite foundation is brought forward, the part above equal settlement surface is considered pile's uprising shear failure of Terzaghi's mode, the part below equal settlement surface is considered pile's uprising shear failure of Meyerhof's model, through assumption, the formula of limiting bearing capacity is educed and engineering practice.
