조립질 화강암 연암지반 발파진동 추정식 산정에 관한 실험적 연구

For ground vibration can cause the physical damage to existing buildings, it has always danger of huge accident. Because the characteristics of ground vibration is different by the field condition, it is difficult to prevent the accident due to the vibration. Nevertheless, it is necessary to establish the prevention plan to minimize the damage by generating the vibration below the limitation, From this point, the blasting job could be carried out through blasting pattern design and control. This study aims to propose the prediction equation of blasting appropriate for the constructive granite ground by measuring and analysing the blasting data of 954 times and the results can be applied for the blasting in the same ground type.
