摘要
重庆恒大城首期二标段A区小高层项目场地为超深回填土区,平均回填深度30m,最深达45m,多为垃圾废弃材料堆填。采用强夯法加固地基,并在基础底设900mm厚褥垫层,将用于路桥建设的土工格栅用于建筑物地基,形成刚柔结合的地基基础,地基承载力和不均匀沉降满足要求,取得较好的综合经济效益。
High-rise building in a area of Chongqing Hengda City （bid II） locates at supper-deep filled area,and it is mainly filled with 30m depth garbage （45m in maximum）. Rigid and soft compounding foundation is formed by reinforcing with dynamic consolidation method,setting cushion with 900mm in thickness under the foundation and adopting geotechnical grille which is commonly used in road and bridge projects. It proves that the bearing capacity and differential settlement of foundation can reach requirements,and good economical benefit can be gained.
