摘　　要：混凝土面板堆石坝是我国当前水利工程建设常用的坝型之一。由于坝体选址的限制,一些面板堆石坝需要修建在狭窄的河谷地区。相较于常见的宽阔河谷,峡谷地区陡峻狭窄的地形增加了坝体变形控制与面板开裂控制的困难,为大坝的建设及正常安全运行带来了诸多挑战。本文总结了当前国内具有代表性的峡谷区面板堆石坝工程建设与相关理论研究的进展,探讨了坝体变形与面板开裂的机理及应对措施,可为相关工程提供参考借鉴。Concrete face rockfill dam （CFRD） is one of the most popular dam types in dam construction in China. Some CFRDs have to be built in narrow valleys due to the restrictions of geographic features. Compare to those built in wide valleys, CFRDs built in narrow valleys are with difficulties in deformation control and concrete crack control. Overview of the practical and theoretical progress in CFRDs constructions in narrow valley is summarized. The mechanism and remedy strategies for deformation and crack are highlighted. References for related engineering constructions are provided.
