Investigation of depth effect for underwater blasting-induced vibrations propagation;

Abstract

The underwater blasting technology improvement that especially gained way in last 50 years, this process accelerated due to some humanitarian needs and obligations. Underwater blasting has environmental effects as surface blasting, vibration is one of them. The propagation of blasting-induced vibration which is known to vary depending on distance, amount of explosive and geological features. In this study, effect of depth was investigated for propagation of underwater blasting-induced vibrations. In accordance with this purpose, in two different periods, underwater blasting at different depths were analyzed statistically in the same area and then depth effect discussed for impact of underwater blasting-induced vibration. As result of the test, the effect of depth could not be determined to propagation of vibration for underwater blasting. Also, PPV and SD equations were used for prediction of blasting-induced vibrations. Then, blasting-induced vibration propagation of blasting were examined within the scope of this study. © 2017, Hacettepe Universitesi Yerbilmleri. All rights reserved.
