摘要
随着当前城市地下空间的开发和利用,产生了许多深基坑。现场监测是确保基坑施工开挖安全的关键,尤其是结构的横向位移监测。介绍了基于光纤监测的全过程,包括早期安装、设备调试、数据采集、数据处理和数据分析。通过将光纤监测数据与手动监测数据进行比较,分析了深基坑开挖的变形情况,探究了超深基坑开挖的变形规律,证明了光纤监测在深基坑开挖中的优势。同时借助智能基础设施服务系统的支持,监测数据可以传输回计算机终端,实现远程监测。
The development and utilization of urban underground space are generating many deep excavations,and on-site monitoring is a critical issue to ensure the safety of excavation,especially the lateral displacement monitoring of the structure.This paper introduces fiber optic monitoring,including early installation,equipment debugging,data acquisition,data processing,and data analysis.By comparing the fiber optic monitoring data with manual monitoring data,the deformation of deep excavations is analyzed,and the deformation law of ultra-deep excavation is obtained,which also demonstrates the advantages of fiber optic monitoring in deep excavation.Finally,with the support of the Intelligent Infrastructure Service System(iS3),monitoring data can be transmitted back to computer terminals for remote monitoring.
