摘　　要：以西南某卵石地层深基坑工程为例,采用FLAC3D软件对该卵石地层深基坑的变形特征进行了三维数值模拟分析,研究了卵石地层深基坑的变形特点,模拟结果表明,基坑开挖过程中,卵石地层段侧壁变形明显,位于该段的锚索受力最大,卵石地层深基坑支护重点是控制基坑侧壁卵石土体的位移。Taking southwest a gravel stratum deep foundation pit engineering as an example, using FLA3D software made 3D numerical simulation analysis on the deformation features of the gravel stratum deep foundation pit, researched the deformation characteristics of deep foundation pit gravel stratum, the simulation results showed that, in deep foundation pit excavation process, the side wall deformation of gravel stratum section was obvious, the cable force was biggest located in the segment, the focus of gravel stratum of deep foundation pit support was control of the dis- placement of foundation pit side wall gravel soil.
