摘　　要：我国南方地区水资源配置工程是通过退还被城市挤占的农业灌溉和生态用水量,以改善受水地区的农业灌溉和生态环境用水条件为任务的大型水资源配置工程。预应力钢筒混凝土管(prestressed concrete cylinder pipe, PCCP)的稳定运行直接关系到城乡供水安全。文章依据我国南方地区水资源配置工程中施工第8标段的实践过程,深入剖析PCCP柔性接口发生渗水现象的原因,并据此提出一系列针对性的修复方案,通过对比修复效果确定修复方法,旨在为类似工程提供参考。The water resources allocation engineering in the southern region of China is a large-scale water resources allocation engineering which is tasked to improve the agricultural irrigation and ecological environment water consumption conditions in the water receiving area by returning the agricultural irrigation and ecological water consumption occupied by the city.The stable operation of Prestressed Cncrete Cylinder Pipe(PCCP)is directly related to the safety of urban and rural water supply.Based on the practice process of the construction of the eighth bid section of the water resources allocation engineering in the southern region of China,this paper deeply analyzes the causes for the seepage phenomenon of the PCCP fl exible interface,puts forward a series of targeted repair schemes accordingly,and determines the repair method by comparing repair effects,aiming to provide reference for similar engineering.
