摘　　要：以天津滨海新区某拟建场地人工渗流场为研究对象,对研究区的水文地质条件进行分析和概化,用GMS7.1建立了水文地质概念立体模型。调用GMS7.1中的MODFLOW模块建立地下水流数值模型并求解,得到研究区的各项水文地质参数,再现并预测了研究区的地下水流场情况。计算结果表明,利用GMS建立的人工渗流场概念模型求解的各项水文参数较为精确,与现场实际情况吻合。同时,利用GMS进一步确定了合理的开采水方量及开采时间,为有效防治抽灌水引起的土体变形提供了理论依据。Taking a proposed artificial seepage field in Binhai, Tianjin as study object, a hydrogeological solid conceptual model is set up with GMST. 1 based on the complete analysis and summary to geological and hydrogeological conditions of test area. Then a groundwater numerical model is set up by calling the MODFLOW module of GMS7. 1 and is solved. The hydrogeologic parameters of test area are obtained and the groundwater flow field in test area is reproduced and predicted. The calculation results show that the hydrological parameters of artificial seepage field model established by GMS are accurate and consistent with actual situation in the field. At the same time, the reasonable amount and time of water pumping are further determined by using GMS, which provides a theoretical basis for the effective control of soil deformation caused by water pumping.
