Examples
- An aquiclude stores water but does not transmit significant amounts .
一个不透水层只存水但不能大量导水。 - An aquitard stores water and transmits enough water to be regionally significant but not enough to supply individual wells .
弱透水层存水且区域性地传导大量水，但不能充分供给每个井。 - The calculation result effectively indicate the change rule with the time and space of water table of the aquifer , soft dank aquifer , parameter in process of wells work in the pit
计算成果较好地刻画了基坑井群的实施过程中含水层、弱透水层水头、参数的时空变化规律。 - ( 4 ) water flow model experiment is made and hydraulic pressure variation is observed , " the detainment and displacement " of semipervious aquifers in the process of decreasing water is also studied
(四)模拟二元结构土层，进行土样渗流试验，观测水压的变化，研究弱透水层承压水在降水过程中的“滞后和位差”现象和问题。 - For impervious layer , the anti - inrushing stability of the pit is analyzed from the plastic damage of soil , but for semipervious layer , the anti - inrushing stability of the pit is analyzed from the seepage damage of soil
坑底为不透水层土时，应从土体发生突涌塑性破坏的角度进行分析；坑底为弱透水层土时，应从土体发生突涌渗透破坏的角度进行分析。
