摘　　要：地面沉降是控制高速铁路安全运营的关键问题。因此，查明地面沉降对高速铁路安全运营的影响有着重要的理论和实际意义。本文针对郑徐高铁商丘段地面沉降情况，调查收集了铁路沿线地下水开采利用情况以及地面沉降的现状，在此基础上，采用VisualModflow软件在现状开采条件下对研究区地下水位变化进行数值模拟。同时，结合该地区地面沉降量与地下水位变化间的相互关系，计算出不同开采量、开采时间下的地面沉降量，得出了郑徐高铁穿过部位的预测沉降量。The first issue to control the safety of high-speed railway operation is to solve the problem of regional land subsidence. So, it has great significance in theory and practice to research the regional ground subsidence along the railway line. In view of the land subsidence of Zhengzhou-Xuzhou High-speed Railway （ZXHR）, the situation of groundwater exploitation and land subsidence is investigation and collected. The numerical simulation research on groundwater level changes caused by ground water exploitation was carried on with Visual Modflow. Based on the research above, according to the correlation between land subsidence and groundwater exploitation amount were calculated and the land subsidence amplitude and velocity under ZXHR were predicted. The countermeasures can be supplied for the safety of high-speed railway.
