摘　　要：测压管是河床式水电站混凝土坝重要的渗流监测设施,对于无法满足监测需求的测压管,应采取扫孔或重新钻孔的措施恢复其功能。在运行期混凝土坝上钻孔风险极大,类似工程较少。通过工程实例,从钻孔选点、钻孔施工、测压管埋设等方面,探讨了运行期河床式混凝土坝钻孔埋管实施的关键技术,分析了工程实施后的监测效果,同时为有类似需求的工程提供技术参考。The piezometer is an important seepage monitoring facility for a concrete dam of river-bed hydropower project.For the piezometer that cannot meet the monitoring requirements,it should be swept or redrilled to restore its function.The risk of drilling in concrete dam during operation is very great,and there are few related projects.Through engineering examples,this paper discusses the key technology of drilling and burying pipe in a river-bed concrete dam during operation,analyzes the effect of monitoring after project implementation,and provides technical reference for projects with similar needs.
