随着南水北调中线工程通水时间的日益临近，研究滹沱河地下水库调蓄对城市地下空间的影响显得尤为迫切。地下水库调蓄引江水后，随着地下水开采量的减少和地表水的入渗，石家庄市区地下水位将逐渐回升，可能对城市地下空间建筑产生一定影响。采用数值法模拟了滹沱河地下水库调蓄后地下水位的变化，并预测了地下水调蓄对城市地下空间建筑的影响。研究表明：在多年平均降水及黄壁庄水库无弃水前提下，滹沱河地下水库调蓄对铁路入地工程、城市轨道交通工程以及城市高层建筑没有影响，但在极端情况下，遇到当地特丰水年份滹沱河河道行洪时，部分城市地下空间建筑将受到浸没影响，需采取必要的应急预警及地下水位调控措施。

With the incoming of the water transfer from Yangzi River to the north part, it becomes very urgent to study the influence of ground-water reservoir regulation totheurbanundergroundspaceafter theproject operation. With thewatertransfer, thedecreaseofthegroundwater exploitationandtheincreaseofthesurfacewaterinfiltrationwillincreasethewatertableinShijiazhuang, whichwillinfluencetheunderground structure constructed in the urban area. It used thenumerical method to stimulatethevariation of the water table and forecast the influence to theundergroundconstruction. Itshowsthatthereisnoobviousinfluencetothesubwayandhigh- risebuildingscausedbygroundwaterreser-voir regulation under annual average precipitation and non discharge from Huangbizhuang Reservoir. However, in the extreme condition, with rich rainfall and flood in the Hutuo River, some urban underground constructions will be influenced by the increased groundwater table and some emergency response should be taken.
