摘要
为研究不同填芯材料对L型填芯箱式挡土墙稳定性的影响,采用了FLAC 3D有限差分软件进行数值模拟研究,通过控制荷载作用,对L型填芯箱式挡土墙在不同填芯材料充填情况下的水平位移、竖直位移以及土压力进行了对比分析。研究结果表明:不同的填芯材料对L型填芯箱式挡土墙稳定性的影响程度呈现明显差异,石灰土填芯相较于黏土填芯能够更好地降低挡土墙位移及土压力,有效减小挡土墙的变形和受力,提升支档结构稳定性,为L型填芯箱式挡土墙的工程设计与施工应用提供了参考借鉴。
The finite difference software FLAC 3D was used for numerical simulation to study the influence of different filling materials on the stability of L-shaped core-filled retaining wall.By controlling the load,the horizontal displacement,vertical displacement and earth pressure of L-shaped core-filled retaining wall under different filling materials were compared and analyzed.The research results show that the influence degree of different filling materials on the stability of L-shaped core-filled retaining wall is obviously different.Compared with clay filling core,lime soil filling core can better reduce the displacement and earth pressure of retaining wall,effectively reduce the deformation and force of retaining wall,and improve the stability of supporting structure,which provides a reference for the engineering design and construction application of L-shaped core-filled retaining wall.
