Three-dimensional seismic face stability of shield tunnels inundrained clay
《Underground Space》2024年第2期26-43,共18页Milad Davoodi Salvador Senent Amin Keshavarz Rafael Jimenez 
This research was funded,in part,by the Spanish Ministry of Science and Innovation under Grant PID2019-108060RB-I00.
Tunnel face stability has received increasing research interest over the past few decades. However, computing time-efficient and safethree-dimensional solutions under seismic loading is still an unsolved problem, whil...
