摘要
混凝土面板堆石坝工程实践表明,一般情况下,趾板不存在抗浮稳定问题。水布垭趾板采用了"标准板+X"的设计思想,即由上游标准板和下游防渗板组成。标准板与常规趾板一样,不存在抗浮稳定问题;而防渗板在我国面板坝实践中尚属新生事物,在上下游水压作用下,通过面板及堆石体传递给防渗板的压力到底有多大,防渗板究竟能否满足抗浮稳定要求,有必要加以研究。
Under common conditions,a concrete facing rockfill dam is not present at stability against flotation.The design pattern of standard facing plus X is used for Shuibuya Dam too slab,namely,it is composed of standard facing upstream and watertight facing downstream.By the action of water pressure upstream and downstream,the pressure transmitted to the watertight facing and rockfill through the slab and rockfill,as well as whether or not the stability resistance flotation is met,are discussed in the paper.
