【摘要】 为确保基坑安全施工并掌握其施工过程中的稳定性，文中在基坑所处环境条件调查基础上，先开展支护设计分析，结合监测结果，通过变形预测评价基坑施工过程中的稳定性。结果表明，基坑周边近接条件相对较为复杂，为确保其稳定性，将其支护方式确定为“支护桩+锚索”,经变形预测得到，基坑后续变形预测值为20.92～24.42 mm,均小于35 mm,这表明基坑在施工过程中处于稳定状态。更多还原

【Abstract】 To ensure the safe construction of the foundation pit and grasp its stability during the construction process, this article first conducts support design analysis based on the investigation of the environmental conditions of the foundation pit, and combines monitoring results to evaluate the stability of the foundation pit construction process through deformation prediction results. The analysis results show that the surrounding conditions of the foundation pit are relatively complex. To ensure its stability, the support method is determined as “support piles+anchor cables”. After deformation prediction, the predicted deformation values of the foundation pit are between 20.92～24.42 mm, all less than 35 mm, which shows that the foundation pit is in a stable state during construction更多还原
