Field monitoring and numerical analysis of shield tunneling considering existing tunnels

More Information
  • Published Date: March 15, 2009
  • Based on the example of Shenzhen shield tunneling under a cable tunnel,through application of the displacement load method to simulate the tunnel excavation and by use of the beam theory of elastic foundation to analyze pipe-soil interaction,the existing tunnel above the subway tunnel considered as a large-diameter pipeline is proposed.The formation response caused by the construction of the left line of the subway is analyzed.The safety of the cable tunnel is evaluated by the relative control standards.It is shown that the numerical results agree well with the measured data,and the cable tunnel is also in a state of safety.It can provide reference for similar projects.
