| Abstract: | This paper suggests a method of nonlinear analysis for the mutual interaction -between the pile cap, the pile and the soil in the layered soils. In the analysis, the working condition of the group piles, their failure characteristics, the influence of the loading level to the yielding sequence of the pile-soil nodes, the transmittance law of the loading from the corner piles to the interior piles as well as the share of loading between the soil and the pile are all investigated and all are verified by concrete examples. The analyses of the pile group in this paper have good feasibility. |
