Simplified analysis for tunnel supports

Webb13 apr. 2024 · There is a wholesome kind of magic that blossoms out of friendships. As Australian writer Markus Zusak pens it, "a snowball in the face is surely the perfect beginning to a lasting friendship.” Whether you are going through a rough patch in life or celebrating simple wins and triumphs, you can always count on your friends to always be … WebbThe analysis focused on the effect of constructing twin tunnels on ground surface settlement, contact pressure between lining and ground, and change in tunnel diameter. Based on the results obtained, it was observed that as the compressibility ratio, c, and spacing between tunnels decreased, the interaction effect between tunnels increased.
