Abstract The present study considers the influence of inclined and eccentric loading on the bearing capacity of a strip footing placed on the reinforced cohesionless soil slope by using lower bound finite element limit analysis technique. The effects of other parameters such as soil friction angle, embedment depth of reinforcement layer below the footing, interface friction angle between soil and reinforcement, and vertical spacing between two reinforcement layers are also investigated. Results are presented as the variation between reinforcing efficiency and various combinations of above-mentioned parameters. The bearing capacity of strip footing reduces under combined effects of inclined and eccentric loading. However, with the inclusion of reinforcement layers at the optimum depth, the bearing capacity enhances significantly. The reinforcing efficacy increases with the increasing value of load inclination. The reinforcing efficiency reduces with the consideration of partial roughness between soil and reinforcement layer. Stress contours are also plotted in the two-dimensional object space to understand the failure mechanism of slopes.

斜荷载和偏心荷载对加筋边坡条形基础承载力的影响

摘要 本研究采用下界有限元分析技术，研究了倾斜和偏心荷载对加筋无粘性土边坡上条形基础承载力的影响。还研究了其他参数的影响，如土壤摩擦角、基脚下方钢筋层的埋设深度、土体与钢筋之间的界面摩擦角以及两个钢筋层之间的垂直间距。结果表示为增强效率和上述参数的各种组合之间的变化。在倾斜和偏心载荷的共同作用下，条形基础的承载力降低。但是，通过在最佳深度处加入加强层，承载能力显着提高。增强效果随着荷载倾角值的增加而增加。考虑土体与加筋层之间的局部粗糙度，加筋效率降低。在二维对象空间中还绘制了应力等值线，以了解斜坡的破坏机制。
