Abu Hamour Tunnel Phase I the First TBM Tunnel in Qatar: The Art of Tunneling in a New World,rehensive geotechnical data collection system on the tunneling project in weak/soft rocks which has been successfully implemented. Results of geological mapping have been presented to show how they correlate to TBM performance. The authors make an attempt to correlate common classification systems:

Reducing the Tunnelling Effect on Adjacent Pile Foundations,ced area near or around the tunnel vicinity to reduce the induced stress and deformation of tunnelling process on nearby deep foundation. The objective of the present study is to numerically evaluate the nature of interaction between the employed tunnelling technologies; the nearby structures founde

Mitigating Foundation Settlement Induced by Tunnel Construction, lines. Tunnel construction in urban areas usually passes in the vicinities of building foundations. Unless sufficient clearances exist, shallow tunneling can cause settlements and/or tilting of adjacent foundations. In most cases, this clearance is not affordable. One of the proposed solutions to r

The Monitoring of Segments Dislocation Deformation in Shield Tunnel Based on BOFDA,t project to ensure the long-term health and safety of tunnels. Regarding to the deformation characteristics of shield tunnel, this paper presents a new method for the layout of sensing fiber based on BOFDA. By analyzing the plane geometry, the relationship between strain and deformation of segment

The main items which control the stability of TBM excavation are face pressure, grout pressure and interaction of lining components with grout
