摘要

Land subsidence is one of the major environmental geological problems in the construction of Daxing new town. In this paper, the characteristics, formation conditions and influence factors of land subsidence in Daxing new town were described. Using Modflow software, land subsidence calculation model was established, and the land subsidence trends were predicted, which provides basis for the construction, planning and land subsidence control of the new town.
