摘要
综述了历来混凝土面板堆石坝坝顶防浪墙设计的各种型式,推荐了宜釆用的防浪墙设计型式。指出了我国现在实际釆用的坝顶宽度较国外为宽,尚有缩窄的余地。文中还研究了"∪"型防浪墙的抗震拟静力法的分析,其抗震安全系数很高,远大于规范规定安全系数(1.20)的要求。
Various shapes of designs for the wave-walls on the crests of the existing concrete-faced rock-fill dams are summarized herein, and then the appropriate design shapes for the wall are recommended. It is pointed out that the width of the dam crest actually adopted at home is wider than that used abroad, so there is still, some space to be contracted. Furthermore, the seismic analysis with pseudo-static approach on the U-shape wave-wall is studied, as its seismic safety factor is quite high, which is far greater than the requirement of 1.20 stipulated in the technical specification concerned.
