猴子岩水电站面板堆石坝堆石体变形控制措施

Control Measures on Rockfill Deformation of the CFRD of Houziyan Hydropower Station

猴子岩水电站面板堆石坝最大坝高223. 5 m,坝址区河谷狭窄,河床覆盖层深厚,地震烈度高,要求采取有效措施,控制大坝堆石体在面板施工后期的变形量。详细介绍了在工程设计、施工过程中针对堆石体变形提出的控制思路、采取的措施,以及实际的实施效果,可为深窄河谷高面板堆石坝的设计与施工提供参考。

The maximum height of the concrete face rockfill dam （CFRD） of Houziyan Hydropower Station is 223. 5 m.Because the river valley of dam site is narrow, the river bed overburden is deep and the seismic intensity is high in dam area,it is necessary to take effective measures to control the deformation of dam rockfill in the later stage of dam panel construction. The ideas, measures and implementation effects of deformation control against rockfill body during design and construction of dam are summarized, which can provide reference for the design and construction of high CFRD at deep and narrow valley.
