摘　　要：以南京市某深基坑支护工程为背景,对基坑变形规律进行了信息化监测与分析,监测数据分析结果表明:基坑施工工况的不断变化导致基坑支护顶部位移、深层土体水平位移、周边环境变形、支撑轴力、地下水位等指标呈现出不同的变化规律;应加强施工过程中的管理和监督,及时关注关键变形指标的变化,防止基坑变形过大甚至出现险情;基坑支护设计方案达到了预期设计目标,实现了动态设计和信息化施工。Based on a deep foundation pit support project in Nanjing,the information monitoring and analysis of the deformation law of the foundation pit were carried out,to the results of monitoring data analysis show that the continuous change of foundation pit construction conditions leads to different changes in the displacement of the top of the foundation pit support,the horizontal displacement of the deep soil,the deformation of the surrounding environment,the axial force of the support,and the groundwater level.The management and supervision in the construction process should be strengthened,and the changes in key deformation indicators should be paid attention to in time to prevent the foundation pit from deforming too much or even in danger;The foundation pit support design scheme has achieved the expected design objectives,and the dynamic design and information construction have been realized.
