Interaction between Groundwater Environment and Urban Under Ground Space during Its Operation

During the whole operation period(usually beyond 50 years),the groundwater environment will change more or less because of natural factors(such as meteorology or hydrology) or manmade factors(such as urban water resources measures),which will lead a sequence of adverse effect on engineering(such as uplift of structure,seepage problem,high hydropressue and settlement).On the other hand,the under ground structure will also change ground water environment vice verso,which will lead a series of environment and engineering problems.The causes,evaluation method and control measures of the problems of the two aspects mentioned above are discussed systematacially in this paper,which may be a reference to evaluate,alleviate or even evade the adverse interaction between groundwater environment and under ground space.
