Estimating Surface Settlements Due to Tunnel Works
Estimating Surface Settlements Due to Tunnel Works
(OP)
Hi,
I am using numerical modeling to estimate ground surface settlements due to tunnel works. I did the modeling in two stages. First, I used Mohr-Columb models to estimate the extents of the medium that is affected by tunnel works, which I assumed determines the disturbed soil region. Second, I replaced the disturbed soil regions with loose material (smaller elastic properties than the original material properties), and used elastic models to estimate the ground surface settlements.
I appreciate any suggestions about the validity of my approach.

BigH: Can you be more specific about Peck works, year, title, etc.
Thanks
