Analytical solution of bearing capacity of circular shallow foundations using upper-bound theorem of limit analysis

针对圆形浅基础 ,根据极限分析中的上限定理 ,选择合适的机动位移速度场 ,推导出地基承载力的上限解析解。绘制上限解析解与粘聚力、内摩擦角的关系曲线。同时根据工程实例 。

On the basis of upper bound theorem of limit analysis, this paper gives upper bound answers of bearing capacity of circular shallow foundations by suitable choice of a kinematically admissible velocity field. The analytical solution curves of the foundation varying with the cohesion C , and the angle of internal friction φ, have been protracted, and the answers are checked by the results of experiments.
