密云水库调蓄工程PCCP段运行期安全监测及成果分析

Safety monitoring and assessment of prestressed concrete cylinder pipe during operation of Miyun Reservoir Regulation and Storage Project

以密云水库调蓄工程PCCP段为研究对象,对运行期PCCP管道接触压力、渗透压力、接缝位移和沉降位移进行监测,并对监测数据整体情况和变化规律进行分析,结果表明该工程处于安全稳定运行状态。监测结果也为工程运行性能和状态评估及运行管理单位科学管理提供了可靠依据。

Targeting at prestressed concrete cylinder pipe (PCCP) of Miyun Reservoir Regulation and Storage Project, monitoring has been conducted to its contact pressure, seepage pressure, joint movement and settlement displacement during operation period, combined with evaluation of overall situation of monitoring data and change pattern. The results indicate that the project is under safe and stable operation condition, which may provide concrete base for evaluation of operation performance and conditions as well as scientific management of the operating units.
