摘要： 重庆龙泉住宅小区拟建一栋7层的居民楼，但该小区曾经发生过滑坡，需对边坡进行切坡处理。在地质环境综合调查的基础上,通过对现状和切坡后的边坡进行稳定性验算，判定可能产生的破坏模式及边坡稳定类型。结果表明：（1）现状边坡暂时处于稳定状态，其安全系数介于1.002~1.188。（2）切坡后边坡的安全性不能满足规范的规定要求，需对边坡采取相应的措施。（3）从施工开始起，对边坡进行变形观测。

Abstract: The proposed sevenstory residential building in Block A of Longquan Residential Development is to be constructed at a fresh historical landslide site. Based on the development plan, the existing slope will be steepened. The stability aspects of the existing slope and the steepened slope are evaluated based on the investigation of the geological conditions, slope topography and the structural aspects of the sliding surface. The possible failure modes are determined. The analytical results indicate that, 1) The existing slope is stable with a factor of safety between 1.0 and 1.2. 2) The safety of the steepened slope could not meet the code requirement and the slope stabilization mitigation is required. 3) The slope construction should be monitored.
