Ground vibrations level characterization through the geological strength index (GSI)

This paper analyses results of trial, construction and quarry blasting, carried out in sediment rock deposits, mainly limestone and dolomite, at the different locations in Republic Croatia. The division of the three test groups was based on the lithology changes and GSI values of the rock units at these locations. The peak particle velocity measurements with 246 recorded events, was conducted during a long period of the six years. Based on results of seismic measurements, were established the empirical relationships between peak particle velocity and scaled distance for each group. In order to establish a useful relationship between peak particle velocity and scaled distance, simple regression analysis was conducted with the Blastware software program from Instantel. The results of this study can be used to characterized ground vibrations level to the environmental, through the geological strength index (GSI).
