Determination of the ground vibration attenuation law from a single blast: A particular case of trench blasting

The general transmissivity law of ground vibrations was studied, and a user-friendly methodology for determining the behavior generated in any rock mass is proposed. study based on single blast trench excavation, analyzing vibration components recorded from two fixed locations. attenuation main variables according to legal requirements, frequency peak particle velocity (PPV), are defined with this novel method, achieving high confidence level simple manner. proposed approach can also have an important impact terms reducing potential consequences surrounding construction required definition mass. Reducing cost time many projects where blasting techniques applied particularly useful design future blasts.
