Abstract :
The aim of this study was to eliminate the environmental vibrations by use of filled trench in administrative building of steel Co. For assessment of the effects of vibration on human, on the each of the three floors of the administrative building, which was overshadowed by vibration, resulting from oxygen unit, 14 points were determined and the induced environmental vibrations to personnel according to international standard organization-2631 were measured in those points. The results of measurements have shown that a ground vibration was over the fatigue in adjacent building at 25 meters of oxygen unit– Decreased Proficiency Boundary and at some points was above the exposure limit. For reduction of the induced ground vibrations to the adjacent building, this research has designed a method using of sand and two layers of Styrofoam filled trench. The measurements done that had before and after done by trench, have shown that, on average the vibration was reducing around 50% to 70%.
