基坑在线监测系统及工程应用实践

Foundation Pit Online Monitoring System and Its Engineering Application

深基坑工程属于危险性较大的工程之一,其监测过程一直都是一项技术复杂、危险系数高、难度大的专题项目。传统人工监测方法不仅时效性较差而且后期耗费大量资源,在实操的过程中也存在很大的安全隐患。而采用自动化监测系统能够自动且实时采集、传输、报警,能够更好地防范风险、保障安全。论文介绍了基坑在线监测系统设计原则和构成,结合北京铁路枢纽丰台站改建工程(主站房)基坑监测工程,阐述了采用Leica TM50+各种传感器实现基坑监测自动化的方法,并对实时监测数据平台、基坑监测预警管理系统进行了介绍。

As one of the dangerous engineering,the monitoring process of deep foundation pit is always a special project with complex technology,high risk coefficient and great difficulty.The traditional manual monitoring method not only has poor timeliness,but also consumes a lot of resources in the later stage,and also has great security risks in the process of practical operation.But automatic monitoring system can provide automatically and real-time acquisition,transmission,alarm,better risk prevention and security.In this paper,combining with the monitoring project of Beijing Fengtai station reconstruction project(station building),describes the method of realizing the automatic monitoring of foundation pit by using Leica TM50+sensors.And this paper introduces the real-time monitoring data platform and foundation pit monitor warning management system.
