摘要
PCCP管道工程是南水北调中线北京段最长的大型输水工程,为两排直径4 m预应力钢筒混凝土管道(包括2条隧洞)。通过对PCCP安全监测设计进行研究,阐述了长距离、超大口径PCCP输水工程安全监测的设计原则、监测项目、详细布置及监测结果分析,为同类输水工程的监测设计提供借鉴,并为超大口径PCCP管道结构安全与质量控制研究提供合理的数值依据。
The PCCP Pipeline Project of Beijing Section of the Mid-route of the South-to-North Water Transfer Project is a large water-transfer project and the longest one within Beijing Section,which consists of two rows of pre-stressed concrete cylinder pipe with diameter of 4 m(including two tunnels).Through the study on the safety monitoring design of the PCCP,the design principle,monitoring items,detailed layout and analysis of the monitoring results for the long distance and super large diameter PCCP water transfer project are described herein;which can provide some references for the monitoring design of the similar projects and then lay a reasonable numerical basis for researching the structural safety and the quality control of the super large diameter PCCP pipeline as well.
