Strength, deformability and permeability of kakiritic rocks from the Gotthard base tunnel被引量：1
《Journal of Rock Mechanics and Geotechnical Engineering》2023年第9期2224-2237,共14页Martin Vogelhuber Erich Pimentel Georgios Anagnostou 
The 57-km long,new Gotthard Base Tunnel(GBT)crosses over a 1.1-km long stretch containing kakirites,i.e.weak rocks which,depending on the degree of tectonisation,may exhibit severe squeezing behaviour upon tunnel exca...

Effect of roughness on the shear behavior of rock joints subjected to impact loading被引量：4
《Journal of Rock Mechanics and Geotechnical Engineering》2023年第2期339-349,共11页Feili Wang Shuhong Wang Wei Yao Xing Li Fanzheng Meng Kaiwen Xia 
We acknowledge the funding support from the National Natural Science Foundation of China(Grant Nos.51879135 and 51879184);the Natural Sciences and Engineering Research Council of Canada(NSERC)through the Discovery Grant No.72031326.
The shear behavior is regarded as the dominant property of rock joints and is dramatically affected by the joint surface roughness.To date,the effect of surface roughness on the shear behavior of rock joints under sta...
