摘要
以上海市区某超长车站基坑为背景,从基坑分区方案、地墙接头设计、支撑系统选择、地基加固方案4方面探讨了软土地区深基坑设计的难点,重点分析了邻近基坑周边老房屋的保护措施,并建立有限元分析模型,从理论和实际监测数据结果可知,专项保护措施满足了周边房屋的变形控制要求。
Based on the foundation pit of a super-long station in Shanghai,the difficulties of deep foundation pit design in soft soil area are discussed from four aspects:foundation pit zoning scheme,ground wall joint design,support system selection and foundation reinforcement scheme.The protection measures of old buildings near foundation pit are emphatically analyzed,and a finite element analysis model is established.The results of theoretical and practical monitoring data show that special protection is achieved.The measures meet the deformation control requirements of surrounding buildings.
