为保证建筑物不发生上浮事故，设计前必须确定保障建筑物安全的地下水水位高程，该高程一般被称为建筑物抗浮设防水位。
In order to insure the safe of the building, the safe groundwater level height, referred as water level for prevention of up-floating in general, must be confirmed before the design stage.
棱体排水的顶部高程应超出下游最高水位，应大于波浪沿坡面的爬高，且不小于下列0.5米。
Its top elevated level must exceed the highest water level downstream, be higher than the wave runup along the slope, and be no less than 0.5 meters.
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.
