摘要： 挡土墙的稳定性与其所处场地的气象，水文、地形地貌、地层岩性、岩土物理力学性质、场地水文地质条件等密切相关。根据挡土墙变形特征分析挡土墙变形的原因，通过对无水和饱水两种情况的挡土墙稳定系数的验算，得出降水是挡土墙变形的重要诱因，从而制定出疏通挡土墙泄水孔、重力式锥坡反压等加固方案。

Abstract: The stability of the retaining walls are usually associated with their site meteorology, hydrology, topography, lithology, soil & rock conditions as well as the field hydrogeological conditions. Based on the analysis of the deformation characteristics of a retaining wall under both saturated and unsaturated conditions, it is concluded that the dewatering is a major reason casing the excessive deformation of this wall. The mitigation design includes clearing the drainage path, placing a gravity berm behind the wall.
