The ultimate bearing capacity of strip footings is achieved by establishing the statically and kinematically admissible slip line field. The method of rigorous characteristics is applied to address the coupling of stress and velocity fields. Meanwhile, the stress discontinuity line is presented to account for the shear strength of embedded soils. The failure mechanism can be determined by solving the boundary value problems, and such the approach avoids the predefined slip surface. The proposed solutions show good agreement with the existing results, and they are mostly located between the upper and lower bound solutions of numerical limit analysis. The results demonstrate that the obliquely or eccentrically loaded boundary conditions sharply decrease the ultimate bearing capacity. Besides, the negligence of shear strength of embedded soils underestimates the ultimate bearing capacity of strip footings, and the associated flow rule yields the larger bearing capacity because of the overestimated soil strength.

采用严格特性法的嵌入式条形基础的斜向和偏心承载力

条形基础的极限承载能力是通过建立静态和运动学允许滑移线场来实现的。采用严格特征法解决应力场和速度场的耦合问题。同时，给出了应力不连续线来解释嵌入土的抗剪强度。失效机制可以通过解决边值问题来确定，这种方法避免了预定义的滑面。所提出的解决方案与现有结果具有良好的一致性，并且它们大多位于数值极限分析的上限和下限之间。结果表明，倾斜或偏心加载的边界条件急剧降低了极限承载力。除了，
