Experimental and numerical evaluation on debonding of fully grouted rockbolt under pull-out loading

International Journal of Coal Science & Technology, 2022
The axial loading in rockbolts changes due to stress redistribution and rheology in the country rock mass. Such a change may lead to debonding at rockbolt to grout interface or rupture of the rockbolt.

Utsu aftershock productivity law explained from geometric operations on the permanent static stress field of mainshocks

, 2017
The aftershock productivity law, first described by Utsu in 1970, is an exponential function of the form K=K0.exp({\alpha}M) where K is the number of aftershocks, M the mainshock magnitude, and {\alpha} the productivity parameter.

Seismicity and seismic hazards

, 2001
Many earthquakes occur along Canada's western margin near the edge of the North American Plate, but others occur within the plate in Arctic and southeastern Canada. Damaging earthquakes have occurred throughout history in both Eastern and Western Canada, and will undoubtedly recur in the future.
