Abstract

Abstract

By considering consolidation and rheological characteristics of Shanghai saturated soils and three soil layers calculated model in which the compressible strata of pile toe is sand,the numerical simulation of settlement characteristics of bored pile and driven pile foundation is carried out by FEM software package(ABAQUS) and the effects of sand layer surrounding the pile in shallow depth on both kinds of pile foundations are analyzed.The effects of piling effect on pile foundation settlement are effectively verified in accordance with the usage of cylinder expansion theory to simulate the excess pore water pressure induced by pile driving.Finally,based on the displaced soil effect in shallow sand layer surrounding the pile induced by pile driving,numerical simulation of positive action of shallow sand strata surrounding the pile to reduce the driven pile foundation settlement is also presented.
- viscoelasticity of soil,
- driven pile,
- bored pile,
