Abstract

This paper presents the findings regarding the displacement-load behavior of both plane strain model experiments’ ultimate load and numerical analyses conducted on unreinforced and reinforced sand slopes loaded with strip footing. The investigated parameters include the impact of the reinforcement and varying eccentricity on the ultimate load and displacement of the strip footing. A group of finite element analyses was performed with the 3D plane strain model and the computer code ANSYS software to validate the results of the model experiments on a slope. The results from both the numerical analyses and model experiments suggested that the use of reinforcement could enhance the load–displacement behavior of the central and eccentrically loaded footings. The load–displacement curves demonstrated that a higher load eccentricity leads to a reduction in the ultimate load of the strip footing. The concordance between the computed and observed results was reasonably satisfactory for the load displacement and the overall behavioral trend.

加固砂土边坡中的中心和偏心基脚的实验和数值研究
本文介绍了对加载条形基脚的无加固和加固砂质斜坡进行的平面应变模型试验极限荷载和数值分析的位移-荷载行为研究结果。研究参数包括加固和不同偏心率对条形坡脚极限荷载和位移的影响。利用三维平面应变模型和计算机代码 ANSYS 软件进行了一组有限元分析,以验证斜坡模型试验的结果。数值分析和模型试验的结果表明,使用钢筋可以增强中心和偏心荷载基脚的荷载-位移行为。荷载-位移曲线表明,荷载偏心率越大,条形基脚的极限荷载就越小。在荷载位移和整体行为趋势方面,计算结果和观测结果的一致性相当令人满意。
