Abstract

ANSYS is used to carry out 3d elastic-plastic finite element analysis on the transmission tower foundation of different pile spacing. Non-thickness contact element is employed to simulate the nonlinear behavior of pile-soil interaction. Drucker-Prager elastic-plastic constitutive model is adopted to represent nonlinear behavior of soil, the pile being assumed to be elastic. Settlement, foundation axial force and soil stress displacement under uplift force and down force, it is possible to reduce the minimum distance of pile reasonably from the results.
