WANG Wei, YANG Min. An improved elastic analysis method of pile foundation under vertical loading[J]. 2006, (8): 1403-1406.DOI: 10.16285/j.rsm.2006.08.036.
The simplified analysis method of single pile subjected to vertical loading combined soil displacement factors matrix in Poulos’s integral equation method with the polynomial linked pile body and pile tip displacement which is deduced from Randolph’s shear displacement method.So the finite difference calculation in integral equation method is out of need herein.The method is more accurate to characterize shear stress allocation than Randolph method.Pile group under vertical loading can also be analyzed with the simplified method.Comparison with Poulos method
Randolph method and Chow’s hybrid method for single pile and pile group analysis show that the simplified method is feasible and accurate.
