问:一、压水試验前测地下水的安定水位,往往要花费很多时間,是否可以加水来帮助地下水位迅速稳定? 答:如果含水層的透水性很强,地下水位本身会很快地趋於稳定,在这种情况下当然不需要加水。反之,如果含水層透水性很弱,加水后一方面会使测量水位的次数增多,以致地下水位要经过更長的时間才能趋於稳定,另一方面会使含水層的化学成分改变。
Q. First, it is often time-consuming to test the stability of groundwater before the water pressure test. Is it possible to add water to help stabilize the water table quickly? A: If the aquifer is highly permeable, the water table itself will tend to drift rapidly In the stable, in this case, of course, do not need to add water. Conversely, if the aquifer is poorly permeable, the addition of water will increase the number of water levels on the one hand, so that it takes longer for the groundwater level to stabilize and, on the other hand, change the chemical composition of the aquifer.
