On a Paradox of Elasto-Plastic Tunnel Analysis [PDF]
, 2018 Elasto-plastic tunnel analysis may produce a paradox in the calculation of ground pressure whereby ground pressures appear to increase in relation to higher ground quality. More specifically, for an overstressed ground in combination with a stiff support,

Roughness evaluation in shotcrete-lined water tunnels with invert concrete based on cases from Nepal
Journal of Rock Mechanics and Geotechnical Engineering, 2018 Most of the existing roughness estimation methods for water tunnels are related to either unlined or concrete/steel-lined tunnels. With the improvement in shotcrete technology, advancement in tunneling equipment and cost and time effectiveness, future ...
