the dam crest height is determined based on static water level, wave run-up, and freeboard. the freeboard is calculated according to the following formula.
坝顶高程由水库静水位加波浪爬高及安全超高决定。坝顶在静水位以上的超高按下式计算。
for those downstream, they protect the space from dam crest to draining prism or to dam heel in event of no prism.
下游面则由坝顶护至排水棱体,无排水棱体时则护至坝脚。
it refers to space during dam crest level; it is above maximum deposited beach face, storage bottom and normal water level as well as under maximum flood level.
某坝顶标高时,最高沉积滩面、库底、正常水位三者以上,最高洪水位以下的空间。
the deformation process curve of the wanjiazhai dam crest exhibits many peaks.
万家寨大坝坝顶各监测点的变形过程是多峰曲线。
therefore the proper plan of the filling of dam body and the arrangement of access roads to dam crest are the key problems to ensure the strength of construction.
因此,合理的坝体填筑规划及上坝道路布置是确保坝体施工的关键技术问题。
characteristic water level and reservoir capacity is fixed, freeboard and dam crest is calculated, seepage prevention of dam body, dam foundation and dam sheeting is discussed.
