| 摘 要： | 针对北京地区天然地基承载力经深宽修正后满足设计要求而天然地基变形无法满足设计要求的特殊工程地质条件,在高层建筑结构下采用减沉疏布CFG桩复合地基设计是切实有效和经济合理的选择.减沉疏布CFG桩复合地基重点考虑在基础结构的墙柱等应力集中部位下进行布桩,其它部位进行大间距非均匀布桩,以此来达到减少地基变形使其满足设计要求的...

| Abstract: | According to special engineering geological conditions that the bearing capacity of the natural foundation in Beijing area which modified by the depth and width can satisfy the design requirements,but the deformation of natural foundation can't satisfy the design requirements,the compound foundation design with settlement-reducing and sparse-layout CFG piles under the high-rise building structure is really an effective and economic scheme.The said compound foundation is emphasized on the pile layout at the ... |
