ANALYSES OF GROUND MOTIONS FROM CONTAINED BURSTS IN GREENSTONE BASALT

摘要

A series of contained burst calculations were performed (1) to evaluate two different approaches for modeling the properties of an in situ rock field, and (2) to examine some of the effects of porosity upon predicted ground motions. The basic material in the study was greenstone basalt. Results of the calculations were compared with the trends shown by ground motion data from a large number of contained burst tests in hard rock media.
