Geotechnical aspects of tunnel lining with segmental joint parameters to improve soil surface settlement prediction

Conventional lining design usually considers tunnel lining as a uniform rigid ring model by implying high partial safety factor on the bending moment which is overestimated, due to inaccurate assumptions. To overcome this problem, investigation on the influence of joints on the behaviour of the glob...
