Descripción
Error in the measurement attributable to coupling has been assessed by the rock-to-mount, or coupling, transmissibility ?i.e. ratio of the velocity of the sensor mount to the velocity of the ground motion? from 2 to 200 Hz, at two velocity levels, 5 and 20 mm/s. Already published data (13 trials) and new gathered tests on a vibration exciter are considered. In this new campaign free placed, sandbagged, and anchored mounts on granite were tested from 1.6 to 40 Hz at one or two vibration levels. Two more techniques, in which the sensor mounts were fixed with thermal adhesive or a combination of duct tape and gypsum plaster, have been also investigated from 2 to 200 Hz at 5 and 20 mm/s. Free and sandbagged mounts lead to a weak coupling of the mounts to rock, with accurate measurements only below 17 Hz for free mounts and 10 Hz for sandbagged in the tested conditions. Above these frequencies, ground motion in the measurement can be modified by a factor of 0.16 to 1.21. Anchored, glued and plastered mounts achieve a stiff rock-to-mount coupling, ensuring consistent measurements for the frequencies commonly found in blasting independently of the vibration level and the mount characteristics.
