Special load combination conditions.

Calculated working condition		Load combination
		Gravity		Upstream full water level	Upstream check flood level	Designed flood level	Sediment	Temperature rise	Temperature drop
		Mountains	Dam
I	12	√	√	√					√
II	13	√	√		√（▽）		√	√
	14	√	√		√（▽）		√		√
III	15	√	√			√（▽）	√		√
