摘 要: 针对南京河西软土地区几个深基坑工程进行研究分析,主要阐述基坑支护结构及地表变形特性。通过对几个工程基坑变形的分析,探讨了深基坑变形的特征,根据基坑支护结构及地表变形公式推导值与实测数据进行对比分析,总结出了支护结构周围地面的沉降及支护结构水平位移的规律。由于基坑工程本身的复杂性、多变性等方面的影响,使所得结论应用困难。本文选择了南京河西地区类似工程进行探讨。由于分析的均为同类工程,因此分析结果具有该类工程项目的普适性,对河西地区的后继类似工程有一定的借鉴作用。这也是将理论转化为实际的一种有效方式,计算结果的近似性对工程有一定的指导意义。
关 键 词: 岩土工程;深基坑;沉降;变形;支护结构

Abstract: Aiming at several deep foundation pit in the soft soil area of Hexi Nanjing, deformation characteristics of supporting structure of foundation pit and ground surface were mainly discussed. By analyzing several engineering foundation pit deformation, the characteristic of deep foundation pit deformation was discussed. By comparing the formula derivation value and measured value of the deformation of supporting structure and ground surface, the laws of ground settlement surrounding the supporting structure and the horizontal displacement of it were summarized. Due to the complexity and changefulness of the deep foundation pit, the analysis results were applied difficultly. The projects analyzed in this paper are similar projects, therefore, the analyzing results have universality in this kind of projects and a certain guiding function for subsequent projects in Hexi area of Nanjing. This is an effective way to transform theories to practical application, the approximation of calculation results has guiding significance to engineering projects.
