방진 모형실험에 의한 진동레벨의 인간 생활권 내 허용 안전거리 비교

In recent years, the construction work has been done in the downtown area. Especially, the shock vibration occurred in these sites can be caused sensuous damage about the human as well as physical damage about the structure. In general, the vibration influence in the human zone was evaluated by the vibration level. In this study, we obtained the relation curve of allowable vibration level(dB(V)) as converting the peak particle velocity(PPV) of vibration component, and analyzed the allowable safe distance before and after the vibration isolation. The results are as follows : The determination coefficients(R 2 ) of vibration level equation was each 0.95, 0.97 depending on the vibration isolation, and also showed a high correlation in all conditions. It was found that the allowable safe distance reduced about 2.2 times before the vibration isolation and about 2.6 times after the vibration isolation when vibration level set up from 65 dB(V) to 80 dB(V).
