面板堆石坝趾板基础开挖施工技术应用

Construction Method of Plinth Foundation Excavation for Concrete Faced Rockfill Dam

目前,面板堆石坝被广泛应用于水利工程建设中,趾板基础是面板堆石坝面板与地基之间重要的连接结构,其开挖施工技术选择的合理性、施工质量的高低将直接影响面板堆石坝整体的稳定性与使用期限。论述了面板堆石坝趾板基础开挖的施工原理,对面板堆石坝趾板基础开挖施工工艺流程和技术要点进行分析,并结合实例应用加以研究,可供同类工程参考。

At present,face rockfill dams are widely used in construction of water conservancy projects.The plinth foundation is an important connection structure between the faceplate and the foundation of the face rockfill dam.The rationality of the excavation construction technology selection and the level of construction quality will directly affect the overall stability and service life of the concrete faced rockfill dam.The paper discusses the construction principle of the plinth foundation excavation of the face rockfill dam,analyzes the construction process and technical points of the plinth foundation excavation of the face rockfill dam,and studies it in combination with the application of examples,which can be used as a reference for similar projects.
