摘要
对于筏-桩-地基土相互作用的分析，提出了一种桩、土沉降计算模型，该模型将桩、地基土等效为一系列弹簧的连接关系。根据这些弹簧之间的相互作用建立了一套简化的桩筏基础的沉降计算公式，该套公式可以计算基础的平均沉降以及桩、筏板分担上部荷载的比例。
For raft-pile-subsoil interaction analysis, a calculating model for pile-subsoil settlement is presented which is a set of simplification formula is established. The total settlement and the shared ratio of piles and raft （box） of a number of buildings are calculated as the examples of the application and show easiness of the utilization clear concept and exact estimation.
