摘　　要：挡土墙是一种保证路基与边坡土体稳定的构造物,它的作用是防止路基边坡土体发生位移与崩塌,对挡土墙安全性的研究是工程设计的基础性工作之一。对此,以仰斜式挡土墙为例,结合工程实践建立了分析模型,模型中考虑了挡土墙高度、基础埋深和墙顶填土高度的因素影响。采用理正深基坑6. 0软件计算,并对计算结果进行敏感度指标分析;最后总结仰斜式重力挡土墙设计的要点。The retaining wall is a structure to guarantee the stability of subgrade and slope soil.Its function is to prevent the subgrade filling and slope soil causing displacement and collapse.The study on the safety of retaining wall is one of the basic works of engineering design.Hence,based on the oblique retaining wall and combining with the engineering practice,the analysis model is established which considers the influencing factors on the height,foundation buried depth and wall top filling height of the retaining wall.The Lizheng deep foundation pit 6.0 software is used to calculate and the analysis on the sensitivity index of the calculated results is carried out.Finally,the key points for the design of the oblique gravity retaining wall are summarized.
