摘要
提出了用有限元 无界元耦合的方法计算大变形条件下桩 土耦合体系的应力和变形.在桩与土接触的界面上设置了一种有厚度的接触面单元,它可以与土体的弹塑性模型相衔接,能合理地反映接触面及其邻近区域剪切破坏带中的变形性状.计算结果与现场观测数据吻合较好,说明该计算方法是可行的.
A coupling finiteinfinite element method is proposed to calculate the stress and deformation of pilesubsoil coupling systems under large deflection. A new kind of interface elements with thickness is inserted in the interface between the soil and pile, which can dovetail with elastoplastic models of soil and reflect the deformation in the interface and its nearby shear failure area reasonably. The result of an example is reasonably in accord with data of onsite observation, verifying the feasibility of the proposed method.
