摘　　要：新疆某狭窄河谷混凝土面板堆石坝,最大坝高106 m,坝长141.3 m,宽高比1.3,坝址区地处河流出山口峡谷河段,河床宽度8~16 m。为改善不良地形地质缺陷,本工程借鉴和吸收了国内外已建面板坝的成功经验,采用了高址墙、贴坡趾板、设置特殊碾压区等筑坝技术,并将上游围堰与混凝土面板堆石坝坝体相结合,取得了显著的经济效益。In a narrow valley in Xinjiang,one CFRD is 106 m high at maximum,141. 3 m long and its ratio of width to height is 1. 3,The dam is seated at the valley outlet where the river valley is narrow and the riverbed is 8 ~ 16 m wide. To improve the unfavorable geological and topographical conditions,the project borrows the successful experience in design of CFRD at home and abroad,the dam building technology such as high water retaining wall,slope plinth and provision of special compaction zone,etc is applied. Furthermore,the upstream cofferdam and the CFRD body are integrated. Accordingly,the outstanding economic benefit is achieved.
