混凝土面板坝趾板建在深厚覆盖层上的技术研究

Technique study about toe slab built on thick overburden layer of concrete face dam

钢筋混凝土面板堆石坝作为一种新兴的土石坝坝型,可以减小坝体断面,节省工程投资,缩短工期,简化施工导流。文中介绍了目前国内外趾板建在覆盖层上面板堆石坝的发展状况,总结了该坝型在设计工作中的一些关键技术,对深覆盖层上面板堆石坝的设计和计算具有借鉴意义。

As a new type of the earth-rock dam,the reinforced concrete face rock-fill dam has the advantages of reducing the dam section,saving project cost,shorting the construction period and simplifying the construction diversion.The paper introduces the recent development status of concrete face rock-fill dam with the toe slab built on thick overburden layer at home and abroad,summarizes some key techniques for the design of the dam type,which has the reference for the design and calculation of concrete face rock-fill dam on thick overburden.
