Abstract
The Beijing section of the Middle Route of the South-to-North Water Diversion Project plays a significant role in the social,economic,ecological,and environmental aspects of the Beijing region.The main structural component of this section is the DN4000 PCCP pressure pipeline,with soil cover thickness ranging from 2.8 to 10.3 meters.During long-term operation,the PCCP pipelines have experienced varying degrees of damage due to issues such as thermal stress,water hammer effects,corrosion,and material aging.Through comparative studies of multiple repair and reinforcement options,an optimal solution was identified to provide a reference for similar projects in the future.关键词
