深层地铁盾构施工地层水平位移动态分析
Dynamic analysis of strata horizontal displacements induced by shield construction of deep tunnel
摘要
Abstract
To study two-phase horizontal displacemerus 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 Ui is even bigger than U2.During design and construction stages, both the two horizontal displacements should be considered.关键词
