Vertical Bearing Capacity Numerical Analysis of Prestressed Concrete Piles Based on Piles and Soil Material Constitutive Model

Abstract

 This research simulates vertical bearing capacity of Prestressed Concrete piles by the theory basis of finite difference method and relevant material constitutive model for its capacity can be affected by soil plug effect significantly. Its Q-s curves are acquired and analyzed. The research indicates that load-settlement relationship of PC piles is proportional function basically within its bearing property. Also the advantages of FLAC 3D software are affirmed when analyzing piles settlement problems.
