摘　　要：天津滨海新区地处京津和环渤海两大城市带的交汇点,逐渐成为北方经济开发开放中心,战略地位重要。由于区内广泛分布有巨厚的松散第四纪沉积层,地下水持续超采,滨海新区当前的地面沉降速率及累计地面沉降量均不容忽视。本文将建立滨海新区地下水-地面沉降土水数值模型,运用GMS软件,模拟南水北调工程天津段通水前后,滨海新区三种不同地下水压采方案下的地面沉降发展趋势,分析预测结果,确定最优化地下水开采方案,实现地面沉降的有效控制。Tianjin Binhai New Area is located in the intersection strip of Beijing-Tianjin Urban Agglomeration and the Bohai Sea Urban Agglomeration, as the gateway of North China for opening-up. However, the current rate of land subsidence and the cumulative amount of land subsidence have been the unfavorable factors of economic development for many years, which is caused by the thick layer of loose Quaternary and excessive extraction of groundwater. This article will build groundwater-- land subsidence numerical model in the whole Binhai New Area, then simulate the groundwater table land subsidence from 2007 to 2020 by GMS, which corresponds to three groundwater exploitation plans beyond the groundwater management of Tianjin before and after the Middle Route of South-to-North Water Diversion Project. Eventually, the simulation results may be analyzed, in order to choose an optimal exploitation program of groundwater resources and land subsidence controlling.
