【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。更多还原

【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.更多还原
