ESTIMATION OF THE VIBRATION LEVEL OF BLASTING VIBRATIONS
Doboku Gakkai Ronbunshu, 1986 This study aims to propose a new predictor of the vibration level of blasting vibrations. The level must be measured by a vibration level meter that satisfies JIS (JIS C1510). We first researched the response characteristics of the level meter, and developed a computer program which could simulate those characteristics. Using the program.
