Assessment of damage zone thickness and wall convergence for tunnels excavated in strain-softening rock masses
Satici, Ozguer; Topal, Tamer (2021-02-01)
There are two fundamental issues in all underground excavations, which are safety and economy. To ensure safety and expedite excavations, level of tunnel wall convergences and damage zone thickness should be predicted befo...

Carbonate platforms spanning intervals of global change provide an opportunity to identify causal links between the evolution of marine environment and depositional architecture. This study investigates the controls on pla...
Melanges through time: Life cycle of the world's largest Archean melange compared with Mesozoic and Paleozoic subduction-accretion-collision melanges
Kusky, Timothy; Wang, Junpeng; Wang, Lu; Huang, Bo; Ning, Wenbin; Fu, Dong; Peng, Hongtao; Deng, Hao; Polat, Ali; Zhong, Yating; Shi, Guanzhong (Elsevier BV, 2020-10-01)
Melanges represent a significant component of collisional and accretionary orogenic belts. We present a comparison of subduction-accretion melanges of different ages to test how melange-forming processes at convergent marg...
