In this research, a numerical algorithm was proposed for evaluating the bearing capacity of rough strip footing rested on horizontal half-plane using the stress characteristics method. The bearing capacity coefficients, the layout of stress characteristic lines as well as the geometric specifications of the plastic and non-plastic regions beneath the footing for different values of internal friction angles have been calculated. The obtained results were in good agreement with those reported in the literature for $$\varphi \le {25}^{^\circ }$$ . The results revealed that by increasing the internal friction angle, the bearing capacity coefficients, as well as the depth of the plastic domain beneath the footing increase and the emergence point of the non-plastic curved wedge moves toward the footing edges. It was also shown that the roughness only affects the bearing capacity factor due to the unit weight and the maximum depth affected by the stress characteristic lines beneath the rough footing was almost $$0.62$$ times the footing's width which corresponds to $$\varphi ={25}^{^\circ }$$ .

用应力特性法评价毛坯条基的静承载力系数

在这项研究中，提出了一种数值算法，用于使用应力特性法评估搁置在水平半平面上的粗糙条形基脚的承载力。计算了不同内摩擦角值下基脚下方塑性区和非塑性区的承载力系数、应力特征线的布置以及几何规格。获得的结果与文献中报道的 $$\varphi \le {25}^{^\circ }$$ 的结果非常一致。结果表明，随着内摩擦角的增加，承载力系数以及基脚下方塑性域的深度增加，非塑性弯曲楔的出现点向基脚边缘移动。
