摘要： 以浙江省某住宅小区的边坡治理工程为案例，通过分析拟建项目的场地条件，提出了边坡治理方案要考虑的因素，拟定了边坡治理工程方案；在治理方案设计中，以支挡结构的安全稳定性为核心问题，采用最危险工况和相应标准荷载组合，运用理正岩土计算各坡段，计算结果显示各坡段均达到稳定状态；此外，还阐述了锚杆、现浇钢筋混凝土挡墙这两种支挡结构的具体设计方法，使治理措施既能保证本身的安全稳定性，达到治理效果，又具有较好的经济效益。

Abstract: This paper presents a case history of the slope stability mitigation design for a residential community in Zhejiang Province. The mitigation procedure is proposed based on the site subsurface conditions, and the factors that are to be considered in a typical slope stability related project. The evaluations are focused on the stability of the supporting structures and the analysis cases consider the most unfavorable conditions with standard loading conditions. The analyses are performed with Lizheng Geotechnical Engineering Version 5.6. The results indicate that a stable condition has been reached in each of the segment. Further, the design aspects of the ground anchor and the castinplace reinforced concrete retaining wall, which they both meet the code requirement and are cost effective, are presented in the paper.
