摘　　要：结合现有边坡加固理论和加固经验,对一紧临道路和8层老楼房且下部有厚度达14m淤泥软弱土层的基坑边坡进行了复合加固设计。通过对边坡稳定性计算、分析,加固后的边坡满足最小安全系数的要求。按照本设计进行施工后,基坑边坡的变形和周围建筑物的沉降均在安全允许的范围之内,保证了地下室结构部分的顺利施工。所提供的加固技术对同类深基坑支护工程具有重要的参考价值。Based on the slope reinforcement theory and experiences,the reinforcement scheme of a slope that is close to a road and an old building with eight-floor in the silt soil with deep fourteen-meters is designed. By means of stability calculation and analysis of the slope,the smallest security coefficients in the reinforced slope are analyzed. During the excavation of the reinforced slope based on this design,the displacements of the slope and the settlements of surrounding buildings are in the scope of security and requirement,and the successful construction of basement structures are guaranteed. The technology provided in this paper serves as a useful reference to the similar engineering.
