Then, you can decide the basic sizes, including those of slope, crest el, crest width, anti-seepage, drainage, protecting slope, and etc.

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。

To ensure safety of the slope and the road at the slope crest, slope stability improvement works are believed to be necessary.

为确保斜坡及坡上道路安全，实在有重新进行巩固的必要。

The results show that crest speed changes with the depth of waters far more complicatedly than the phase speed does:furthermore, it changes with the slope of the bottom.

结果表明，峰速不仅与水底坡度有关，而旦随水深的变化较相速复杂。
