采用板模拟承台、实体单元模拟桩与土 ,通过建立连接板单元与三维实体单元的罚单元解决了两个不同单元连接问题 ,数值检验证明所建罚单元能有效确保不同单元连接处的位移协助问题。在此基础上计算了带台单桩的蠕变沉降、桩身轴力与桩侧摩阻力 ,得到了一些有益的结论 By using the plate simulation cap and the solid element to simulate the pile and soil, the connection between two different elements is solved by establishing the penalty element of the connecting plate element and the three-dimensional solid element. The numerical test proves that the penalty element can effectively ensure the displacement of different elements Assist the problem. On this basis, the creep settlement, pile axial force and pile friction of single pile with platform are calculated, and some useful conclusions are obtained
