摘要
国内2000年后已建和在建的200 m级高面板堆石坝,从堆石料原岩选择、孔隙率控制、坝体断面分区、面板和趾板防裂控制等设计技术方面及碾压设备选型、坝体预沉降控制、施工填筑分期等施工技术方面,采取了一系列行之有效的措施,取得了坝体变形小、面板裂缝少等成效。借此,对300 m级特高面板堆石坝技术作了设想,提出了尚需研究的课题。
The achievements of deformation control in dam body and cracks on concrete face slab are tremendous owing to the completion or under construction of some 200 m high concrete face rockfill dams （CFRD） since 2000. A series of effective measures such design techniques as the rock selection of dam materials, porosity control, the zoning of dam section, crock prevention of concrete face slab and plinth, and the construction techniques such as compacted equipment selection, dam settlement control in advance, Stage construction are adopted, Which gains achievements of less deformation of dam and less crack of face slab Herein; some tentative plans research subjects for 300 m super-high CFRD construction technique are proposed.
