摘　　要：东干渠工程是北京市南水北调配套工程之一,是中心城环线供水系统重要组成部分,承担第十水厂、通州水厂等东部区域供水任务。东干渠工程建设了安全监测系统,监测内容包括环境量、变形、渗流、应力、应变及专项监测等。但监测系统存在监测数据中断、仪器失效及缺少初值等问题。对某典型断面的应力、应变及温度等内观监测数据以及东五环段的沉降监测数据进行了梳理、对比验证分析,明确了监测数据的合理性,初步确定了沉降风险点,为东干渠工程安全监控提供技术支撑。East Main Canal Project is one of the supporting projects of the South-to-North water diversion project in Beijing.It is an important part of the central city loop water supply system and undertakes the water supply tasks of the Tenth Water Plant,Tongzhou Water Plant,and others for the eastern region.The safety monitoring system has been built in East Main Canal Project,which included the environmental quantity,deformation,seepage,stress and strain,and special monitoring.However,there were some problems in the monitoring system,such as monitoring data interruption,instrument failure and lacking initial value.This paper analyzed,compared and verified the data of the stress,strain,temperature and other internal monitoring data of a typical section,as well as the settlement monitoring data of the East Fifth Ring Road section.In this way,the rationality of the monitoring data was clarified and the settlement risk points were preliminarily determined,which provides technical support for the safety monitoring of the East Main Canal Project.
