| Abstract: | A direct solution for displacement and internal?force of non?symmetric pile foundation is obtained based on the principle of elastic center and the method of stepwise mathematics in the paper.The direct solution is easily tabulated for design. Moreover,a formula for the interaction between displacements of the pile?cap is deduced.At the same time,five methods for measuring the non?symmetry of pile foundation are proposed.The results provide a theoretical basis to choice design planes of pile foundation.Some harms occurring in the pile construction are also discussed. |
