Abstract Seismic bearing capacity of strip footings placed near c-φ soil slopes is investigated in this work using finite element limit analysis combined with an adaptive remeshing procedure. In the analysis, the so-called pseudo-static approach is employed to quantitatively describe the seismic effects. Based on the method, the upper and lower bounds of the normalized seismic bearing capacity factor p/γB are calculated and summarized in design tables/charts for practitioner's use. Parametric studies are performed to illustrate the variation of the normalized seismic bearing capacity factor p/γB with respect to all of the problem variables defined in section 2. In addition, graphical results from upper bound analyses are also provided to display the potential failure mechanisms of the footing-slope bearing system under seismic conditions.

c-φ土坡附近条形地基的抗震承载力

摘要 在这项工作中，使用有限元极限分析结合自适应重新网格划分程序，研究了放置在 c-φ 土坡附近的条形基础的抗震承载能力。在分析中，采用所谓的拟静力方法对地震效应进行定量描述。基于该方法，计算归一化抗震承载力系数p/γB的上限和下限，并汇总在设计表/图表中供从业者使用。进行参数研究以说明归一化抗震承载力因子 p/γB 相对于第 2 节中定义的所有问题变量的变化。此外，还提供了上限分析的图形结果，以显示潜在的失效机制地震条件下的基脚-边坡支座系统。
