| 摘 要： | 基坑空间效应影响范围的确定对其支护方案的选择、施工方案的确定以及监测方案的设置具有较强的指导意义。通过对不同基坑空间效应计算模型的分析,基于新的三维滑楔体破坏模型,提出了空间效应影响区长度的计算公式。三种计算方法的比较分析表明,新的计算方法更全面的考虑了影响基坑空间效应的各种因素,计算过程较为简便,且计算结果能较好地符合监测结果。

| Abstract: | The defining of foundation pit spatial effect influencing extension has major guiding significance in supporting scheme selection, constructing scheme determination and monitoring scheme setup. After analyzed different foundation pit spatial effect computing models, based on a new 3D wedge failure model, a spatial effect influem＇mg I,＇ugth computing formula put forward. Comparative analysis of 3 computing methods demonstrated that the new method has considered various factors influencing foundation pit spatial effect, with easier computational process, and can accord with monitoring results. |
