Abstract

Abstract: Settlement of the groud buildings from the tunnel dug expansion was simulated by MIDAS_GTS． Based on the data，settlement of the groud buildings in different places were analyzed． The effect of tunnel expansion on buildings and buidlings settlement was considered; the influence of tunnel excavation on ground buildings radius was calculated．

Key words: tunnel expansion, settlement of groud buildings, FEM, monitoring measurement

摘要： 采用有限元计算软件MIDAS_GTS 对隧道扩建对地面建筑物沉降进行数值模拟，并结合施工监测数据，分析地面建筑物在离隧道轴线不同位置时，隧道扩建对建筑物沉降的影响以及建筑物是否安全; 判断隧道开挖对地面建筑物的影响半径。

关键词: 隧道扩建, 房屋沉降, 有限元, 监控量测
