复杂环境中某软土深基坑变形性状监测分析

Monitoring and Analysis of Deformation Behavior of Deep Foundation Pit of a Soft Soil in Complex Environment

为研究南京河西地区复杂环境中软土深基坑开挖与施工过程,基坑变形和地面沉降等规律,以南京河西南部地区某基坑工程为实例,在整个基坑施工过程进行了现场监测。根据监测结果对土体深层水平位移、管线沉降、周边道路沉降、支撑立柱沉降、支撑轴力变化各测点进行筛选,最后对所选监测数据进行了较详细的分析与总结。

In order to study the complex environment in Nanjing Hexi area of soft soil deep foundation pit excavation and construction process,deformation and ground settlement regularity,the foundation pit project in southern Nanjing Hexi area as an example,through on-site monitoring in the whole process of foundation pit construction.According to the monitoring results of deep soil horizontal displacement,pipeline settlement,settlement of surrounding road,support column settlement and axial force variation of each measuring point were selected at the end of the selected monitoring data are analyzed in detail and summary.
