Smooth-back tunnel liner plate in soft ground

 

Purpose:

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).
