Tunnel Design - Initial Support with Steel Liner Plate

Rating:
6

Description


Purpose of calculation
- To design an initial liner for a tunnel using steel liner plate.
- Hoop thrust capacity of the liner is checked for a specified overburden pressure, hydrostatic pressure, and live load pressure, which consists of either AASHTO H-20 Truck Loading or Cooper E-80 Train Loading (Per AREMA).
Assumptions/Limitations and Conventions
- Surrounding ground consists of granular or cohesive soil (Not rock)
- Tunnel support is 2-flange or 4-flange, smooth-back liner plate.
- Liner plate joints (flanges) are non-compact (not slender)
