... during earthquake. Based on the evidences identified during our field investigation on many rock avalanches, it is found that rock avalanches distributed along the surface rupture may be generated by the seismogenic fault activity directly instead of ground motion. During the earthquake, rock masses...

... no correlation with the damage potential of ground motion to a structure, particularly underground structures. In this paper empirical fragility curves are proposed for deep tunnels using as a measure of ground motion intensity the Peak Ground Velocity (PGV), which is known to be better correlated to damage. 1...

... Rock engineering risk is defined in this paper as a function of the potential ground motion; the vulnerability of the workplace; exposure of people; and a general term - quality of information. The paper describes the development of prototype software that is a combination between an expert...

... seismic waves recorded in solid rock and on the skin of the excavation were analyzed. It was found that the ground mo- tion measured in the fractured ground on the skin was four to ten times larger when compared to the ground motion measured in the solid rock. Two mechanisms of dynamic response have been...
