摘要
将承台与群桩分开考虑 ,通过相互作用影响系数计算群桩沉降 ,根据位移协调和力的平衡条件 ,将群桩的刚度矩阵和承台—土体系的刚度矩阵进行耦合 ,得到群桩 -土 -承台结构共同工作平衡方程 。
Separately considering the pile-cap and the pile-group, settlements of pile groups are obtained by using interaction factors and assuming that the superposition principle applies.According to the condition of displacement compatibility and force equilibrium and by coupling their matrix of rigidity,the calculation equations for piles-soil-cap interaction are established. The inner force of pile-cap is calculated by the numerical method.
