| 摘 要： | 针对盾构掘进过程中引起的两相水平位移,对广州地铁2、8号延长线某区间进行现场实测,将实测结果与数值模拟相结合,计算表明,在盾构通过的不同阶段,平行于隧道方向的水平位移U1与垂直于隧道方向的水平位移U2呈现出不同的变化规律,在1倍隧道直径的区域内,U1位移最大值大于U2位移最大值,两相位移均不可忽略。

| Abstract: | To study two-phase horizontal displacements of strata during tunnel excavation,specific areas are tested in Guangzhou Metro No.2 and No.8 extension project,combining with the numerical simulation with ABAQUS.The results show that there are different laws of two horizontal displacements U1(parallel to the tunnel) and U2(perpendicular to the tunnel) at different phases.The numerical analysis further demonstrates that in the circular region of one time tunnel diameter,the maximum of U1 is even bigger than U2.D... |
