【摘要】 本文首先简要介绍某出现较大水平位移挡土墙处的地层分布情况及特征,针对挡土墙支护体系所产生的位移问题,建立相应概化计算模型,采用极限平衡分析法进行挡土体系整体稳定性分析,采用简化自由沉降计算方法分析了不同填方堆载工况下,堆载沉降对挡墙基础差异沉降、结构不均匀变形的影响,将计算结果同实测值进行对比分析,并提出相关结论和建议。更多还原

【Abstract】 In this paper, subsoil distribution character of the retaining wall is first presented in brief. Aimed atdisplacement of retaining wall, the correlative analysis model is put forward. Then foundation stability is analyzedby means of limit equilibrium analysis method and different settlement of retaining wall induced by upper soilfillis analyzed by means of simply settlement calculation method. The calculation results are contrasted and analyzedwith monitoring value, and the relative conclusion and technical suggestion are presented in this paper.更多还原
