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。
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.
其次拟定坝的基本尺寸，包括坝坡、坝顶高程、坝顶宽度以及防渗体及排水设备、护坡等的尺寸，使之满足土石坝的工作要求。
Then, you can decide the basic sizes, including those of slope, crest el, crest width, anti-seepage, drainage, protecting slope, and etc.
针对除险加固措施，确定了水库特征水位与库容，计算了坝顶超高及坝顶高程，探讨了坝体和坝基防渗、坝面护坡及防冻等问题。
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.
