| 摘 要： | 针对苏州轻轨一号线盾构隧道的施工情况,采用三维有限元数值模型,研究了盾构施工对不同刚度桩体的影响.计算结果表明:当盾构施工时,不同刚度桩体均偏向隧道移动,在隧道轴线处的横向位移均为最大.桩身横向位移最大值、竖向位移随桩体刚度增大而变小,桩身轴力、弯矩则随桩体刚度增大而逐渐增大,桩身最大负弯矩均出现在隧道轴线位置处.在盾...

| Abstract: | The numerical analysis is carried out to study the influence adjacent sheild tunnel construction on light-railway line 1 in Suzhou on the single pile with variable stiffness,The results of numerical simulationing show that the pile move toward the tunnel,the lateral deformation of the pile is greatest in the tunnel center.The pile lateral and vertical deformation becomes smaller with the pile stiffness increasing.Pile axial force and bending moment becomes greater with the increasing of the pile stiffness,t... |
