摘　　要：猴子岩面板堆石坝是目前世界第二高面板堆石坝,河谷特别狭窄,设计过程中遵循"变形控制+变形协调"、"全生命周期设计"两大设计理念。在狭窄河谷高面板坝变形控制与变形协调技术的探索中,取得"河床趾板设置基座混凝土结构、取消坝体次堆石区、混凝土面板设置永久水平缝、新型监测技术、低热水泥配置面板混凝土、施工期坝体分级抽排水"等多项技术创新成果,可供200 m级或更高面板堆石坝的设计借鉴。The Houziyan Dam is the second highest CFRD in the world. As located in special narrow valley, two design concepts of ＂Deformation control ＋ deformation coordination＂ and ＂Full life cycle design＂ are followed in its design. The dam construction has achieved several technological innovations about deformation control and deformation coordination of high CFRD at narrow valley, such as setting backfill concrete structure for the foundation of toe slab at riverbed, cancelling secondary rockfill area, setting permanent horizontal joints for concrete face, new monitoring technology, using low heat cement for panel concrete, and graded pumping and drainage of dam body during construction. These achievements are worthy of design reference for 200 m-high or higher CFRD.
