Abstract:

Considering the nonlinear interaction between soil and supporting－structure in soil layers for deep excavation designs, p-y curves of supporting pile and soil was proposed according to concentrated force spring model. Based on piles shaft deflection differential equation of the general elastic foundation beam and considering that the deformation of anchor is compatible with the anti-slide pile’s deformation, a differential equation of the piles with prestressed anchor cables considering the nonlinear interaction is derived. Adopting finite difference method to calculate internal force and deflection of supporting piles. Finally, in comparison with the other methods, the calculated results of engineering example indicate that this paper is satisfied for engineering calculation.
