以大兴新航城地区为主要研究对象,利用建立的地下水—地面沉降模型,得出了以《北京市地面沉降防治规划(2013-2020年)》为目标,新航城地区2020年实现规划目标的地下水开采方案。计算表明,将礼贤、榆垡、庞各庄的第一、第二含水层开采量减少30%,其余地区均减少开采量的10%,第三含水层停止开采条件下,将满足《北京市地面沉降防治规划(2013-2020年)》中2020年的规划目标。
This paper states the optimized groundwater development plan based on land subsidence control with the help of groundwater-subsidence model. The results show that by an 30% cut of groundwater pumping of first and second aquifer and 100% cut of third aquifer in Lixian, Yufa and Panggezhuang areas the land subsidence will under the amount that mentioned in the The Planning of Land Subsidence Prevention in Beijing(2013-2020).
