摘要: 南水北调中线工程北京惠宁段采用了PCCP管道输水,经长时间运行,PCCP管道相继出现了断丝、管壁开裂、局部不均匀沉降等病害。本研究针对惠宁段工程中PCCP管道常见的工程地质缺陷,开展了以高密度地震映像及面波法为主的浅层地震试验,得到了PCCP管道及基础垫层的物性特征,准确排查了管壁裂隙及地质不密实隐患,为排查PCCP管道病害提供了宝贵经验。Abstract: Prestressed Concrete Cylinder Pipe (PCCP) is used in the Huining section in Beijing in the middle route of the South-to-North Water Transfer Project.After having worked for a long period,the PCCP pipelines have successively suffered the damage of wire breakage,concrete cracking,and local uneven subsidence.Aiming at the common engineering geological defects of the PCCP pipelines used in the Huining section,this study carried out shallow seismic tests based on the high-density seismic imaging exploration and the Rayleigh wave method.As a result,the physical properties of the PCCP and cushion areas were obtained,accurate troubleshooting of the fractures developing on the pipe wall and geologically uncompacted areas were performed, thus providing valuable experience for the investigation of the damages to PCCP.
