采用特征值法，计算了粗条形基础的承载力系数Nγ。分析是通过考虑一个弯曲的非塑性楔子下的基础基础，由弯曲的滑移线是切向基础的基础在其任何边缘和倾斜在一个角度π/4 - φ /2与垂直对称轴。文献中关于粗糙基础的现有理论，通常在基础下方使用三角形楔，与本贡献的结果相比，通常发现它们提供了更大的Nγ值。关键词：承载力，基础，破坏，数值模拟，塑性。
By using the method of characteristics, the bearing capacity factor Nγ was computed for a rough strip footing. The analysis was performed by considering a curved nonplastic wedge under the foundation base bounded by curved slip lines being tangential to the base of the footing at its either edge and inclined at an angle π/4 - ϕ/2 with the vertical axis of symmetry. The existing theories in the literature for rough footings, which usually employ a triangular wedge below the footing base, were generally found to provide greater values of Nγ as compared with the results obtained in this contribution.Key words: bearing capacity, foundations, failure, numerical modeling, plasticity.
