Research on the Factors Affect the Settlement of Soft Pile in Double-Layered Foundation

Abstract:

The pile work on the complex properties of three-dimensional finite element analysis has been made by building-up one 4x4 soft pole. Having studied on the factors which affect the flexibility pole compound foundation settlement factor in foundation, include the level of vertical load, elastic modulus of the pile, cushion thickness and elastic modulus. The results show that: the impact of soft pile settlement of the factors, the level of vertical load and pile elastic modulus greater impact cushion modulus of elasticity and thickness of the less affected. As for the pole body elasticity modulus and the bed course elasticity modulus, the compound foundation existence is controlled give value preferential treatment most subsides, the bed courses among them almost can be ignored since effect is less.
