Developing a universal tunnel span classification from global tunnel databases

Deep Underground Science and Engineering, EarlyView.
A universal tunnel span classification system is introduced that incorporates tunnel span, cross‐sectional area, typical tunnel types, and intended uses. Representative flatness ratio values are also provided for each span class. The classification is derived from a comprehensive database of 450 tunnel profiles from 47 countries.
