ground water

Interlayer oxidized zone and argillite-sisandstone-argillite sequence occur in red clastic rock formation with ideal artesian and circulating system of ground water.

在红色碎屑岩建造中有层间氧化带和“泥-砂-泥”结构发育，并有良好的地下水承压和循环体制，是地浸砂岩型铀的有利地。

After the Three Gorges Reservoir impounded, due to the rise of ground water, the flabbiness layers in landslides will become soft and collapse when they meet water.

三蓄水后,由于水位上升滑坡地的软弱层遇到水就会变软并引起滑塌。

The resistance to float relates to the attributes and conditions of the ground water, the pressure and floatage of water, the change of water level and the sudden supplement of water.

结构抗浮验算与地下水的性状、压力和浮力、下水位变化的影响因素、外补水有关。
