现浇混凝土在苗家圈水库大坝上游护坡中的应用

在水库除险加固设计方案中大坝上游护坡一般为千砌石护坡。随着全国重点中小型病险水库除险加固的全面展开，再加上工期紧、任务重，一旦大坝上游护坡处理效果不好，将会影响工程进度，以至影响防汛安全。苗家圈水库大坝上游护坝方案由原来的干砌石护坡变更为现浇混凝土护坡，效果良好，值得类似工程借鉴。

Application of cast-in-situ concrete on upstream slope protection of Miaojiaquan reservoir dam

During the design of reservoir risk-removal and consolidating engineering, upstream slope protection always use masonry facing. While national major middle and small reservoir risk-removal and consolidating engineering comprehensively launch, once upstream slope protection make improper results, it could impact not only project progress, but also safety of flood control. The scheme of upstream slope protection changes from masonry facing to cast-in-situ concrete, which it is worth to be recommended.
