Abstract：Research purposes：Taking Beijing-Tianjin Intercity Railway as an example, this paper studies the impact of the regional ground subsidence caused by pumping up underground water on the linear project. Using the three-dimensional calculation software-Processing Modflow for groundwater seepage and ground subsidence coupled model, the coupled model for regional groundwater flow field and ground subsidence is established for the chosen area along railway, where the regional ground subsidence is serious. The modified model is applied to predict the regional ground subsidence.
Research conclusions：With the measured values, the model is verified. The simulation results of subsidence center and settlement value are basically consistent with the real measured results. The model is applied to predict the ground subsidence with the different schemes of pumping up the underground water. The predicted results show that proper pumping up the groundwater can reduce the regional ground subsidence volume, the subsidence gradient and the unevenness of the ground subsidence.
