其他摘要：The problem of plate-pile-soil interaction. under linear elastic analysis, is represented by Boundary Element Method. The mobilized surface of half space of problem is discretized into triangular elements where the subgrade reactions on domain of boundary element are approximated by linear function. The piles have a finite axial rigidy that are discretized four nodal points. The shear stress that acts along the shaft is assumed to have a quadratic distribuition. The normal stress that acts on the tip of pile is assumed to have an uniform distribuition on its area. The union bending plate that caps the top of pile is assumed to have only rigid body moviment.
