摘　　要：文中以某综合性住宅项目为例,对开挖基坑的地表沉降分布、影响进行分析。结果表明,随着土体的破坏,其力学性能逐渐降低,导致地表沉降增大,基坑开挖方向发生变化。由于土体破坏是引起地表沉降的重要因素,因此在计算深基坑开挖地表沉降时,考虑土体破坏是有意义的。Taking a comprehensive housing project as an example,the distribution and influence of soil failure on the surface settlement of excavation foundation pit were analyzed.The results show thatw ith the development of soil failure,the mechanical propertie sof soil gradually decrease,resulting in the increase of surface settlement and ht e change of excavation direction.Because soil failure is an mi portant factor causing surface settlement,it is meaningful to consider soil failure when calculating surface settlement of deep foundation pit excavation.
