摘要
提出了一种新型桩、土相互作用的地基模型 ,这种模型是应用了本文推导的位移系数来求解群桩中每根桩的荷载分配系数 ,以及应用Geddes的应力系数计算桩、土地基的柔度矩阵。同时 ,用这种模型分析了桩箱 (筏 )基础与地基土的共同作用。通过实例比较 。
A new model for the subsoil-pile interaction is proposed in the paper The model includes two courses First,the load distribution factor of pile is computed by the suggested displacement factor Then a flexible matrix of foundation including soil and pile is obtained by Geddes stress factor The new model can be extended to analyze the problem of interaction of the subsoil and the piled box(raft)foundation Two numerical examples are compared with that of the test The results have shown that the computed results are reliable
