Model Tests of Trigger Effect on Rock Faults

Аннотация

Three influences on physical modeling results of unstable dynamic displacements along fault edges under triggered relaxation are considered. The fault filler is assumed to be quartz sand placed in-between moving tiff and rough plates. This quartz sand interlayer is subject to variation in compaction, to relaxation from stresses and to a burst air flow across the interlayer to simulate gas rush in the fault. The relaxation periods in the compact sand packing under the influence of the gas flow are determined.
