| 摘 要： | 以软土地区盾构穿越既有隧道的几种典型工况为背景，借助三维数值模拟的方法，计算分析了既有隧道存在对盾构掘进引起深层位移场的影响规律。由计算结果可知，既有隧道的存在使得盾构掘进引起地面横向沉降影响范围明显增大，但沉降量则减少；从保护既有隧道的正常运营的角度来看，穿越既有隧道的净间距应大于1.0D。

| Abstract: | Based on several typical conditions on shield tunneling through existing tunnels and using the method of numerical simulation, the influence of tunnels on deep displacement field caused by shield tunneling is studied. It is shown that the range of ground horizontal settlement is significantly increased and the value of settlement is reduced as the existing of tunnel. For protecting the existing tunnels, the net distance between new tunnel and existing tunnel should be greater than 1.0D. |
