Abstract

This paper has presented the background for the use of damage criteria for rock tunnels determined from explosive testing. The following conclusions are tentatively advanced. (1) The magnitudes of transient strains and particle velocities necessary to damage lined tunnels are only found within a few kilometers of the fault causing the earthquake. (2) At the small epicentral distances associated with particle velocities sufficiently high to damage tunnels, permanent earthquake induced strains are likely and thus should be considered in design. (3) Strains are a fundamental index of tunnel damage caused by earthquake or explosively induced ground motions. Explosively induced compressive wave strains may be translated to equivalent earthquake shear and surface wave strains.
