中文摘要：
针对长江三角洲第四纪松散沉积层厚度大、地下水位高、地下水量丰富，地下水流动状态复杂等特点，利用深基坑降水试验推求水文地质参数。采用Visual MODFLOW三维有限元差分计算软件，以上海地铁七号线新村路站深基坑降水为例，建立了多层含水层地下水模型，提出了深基坑最优地下水降水方案。
英文摘要：
The Yangtze River delta region has a thick deposits of the quaternary sediment layer, high groundwater table, abundant groundwater recharge, and complicated groundwater flowing condition. In this paper, a groundwater pumping test in a deep foundation pit was conducted to determine hydrogeological parameters. The 3-D groundwater flow model - Visual MODFLOW, was used in the pit area of the Xincun Station along 7th line of Shanghai subway. A multi-layer groundwater model was developed to determine the optimal dewatering scheme.
