摘要: In this paper, a nonlinear mathematical model for analyzing dynamical response to the large deformation of piles with initial displacements is firstly established arc-coordinate, and it set integral-differential equations, in which, Winkeler used simulate resistance soil pile. Secondly, new auxiliary functions are introduced. The differential-integral equations transformed into differential quadrature method (DQM) finite difference (FDM) applied discretize spatial time domains, respectively. Then, Newton-Raphson solve discretization algebraic at each step. Finally, numerical examples presented, responses piles, including configuration, bending moment shear force, graphically illuminated. calculation, two types loads applied, effects parameters on analyzed detail.
