Application of Shakedown analysis to bearing capacity and stability problems of foundations subject to variable loads

一般说来，外力在时间和空间上都不是恒定值。建立了安定分析的公式，并将其应用于变荷载作用下浅基础的承载力问题。结合安定性分析，讨论了强度折减法的力学解释和应力场特殊离散化的改进。这些结果将有助于基础结构的先进和复杂的评估

In general, external forces are not constant values both in time and in space. Shakedown analysis is formulated and applied to the problems of bearing capacity of shallow foundations under variable loads. In the conjunction of the shakedown analysis, mechanical interpretation of shear strength reduction method and improvement of special discretization of a stress field are also discussed. These results will contribute to the advanced and sophisticated evaluation of foundation structures
