  • In this case of "Seongnam~Yeoju double-lanes railroad construction", there were resident houses and gas pipe which were concerned about damages from vibration and noise. Especially, gas pipe which is a diameter of ${\varphi}500mm$ was located under the ground along upside road. The limit of vibration was 1.0cm/sec to protect gas pipe. The electronic blasting systems have been used to control vibration & noise not only gas pipe but also resident houses. The results of tunnelling were successfully conducted with effective vibration control and quick excavation by electronic blasting without any damages to adjacent facilities.

  • This paper presents design and performance evaluation of MR damper for the reducing vibration of a flexible pipe conveying fluid. A novel type of MR damper which is suitable for pipe vibration characteristics is proposed and the MR damper is mathematically modeled and its damping force characteristics are evaluated. The vibration control performance of the MR damper associated with The cantilever pipe system is evaluated.
