In contemporary society, vibration and noise in the road nearby buildings have become social problems as vehicles operation has increased. Especially, in the case of the building used to art performance, available suitability of the building is tested by the indoor noise class. Therefore, the purpose of this paper is the measurement of the structure-borne noise of Seoul Art Center nearby Umyeonsan tunnel and analyzing the effects of countermeasure to it. To measure the effects of countermeasure, not only structure-borne noise is measured, but also the vibration is measured, before and after the construction of pavement using pad and porous asphalt. Consequently, the sound pressure level in art center 1st floor is reduced after mat pavement method, structure-borne noise that was high in 25Hz wide-band before pavement decreased regardless of experimental vehicle's velocity. Using porous asphalt pavement the noise was reduced about 3 dB(A).

유성일대 화강암, 팔당일대 호상 편마암 및 사북일대 퇴적암 지역에서 동탄성계수와 탄성파 속도와의 관계를 밝히기 위하여 완전파형음파검층을 통해 이들 암상에서 탄성파 P파와 S파 속도를 측정하였다. 또한 유성일대 화강암과 팔당일대 편마암 지역에 대해서는 일축압축강도와 포아송비를 실내시험에서 측정하였다. 실내실험 자료에서는 팔당 호상편마암 지역의 탄성파 P파 및 S파 속도가 유성의 화강암 지역보다 높게 나타난 반면, 포아송비가 낮은 값을 보이므로 포아송비의 증가함에 따라 탄성파 P파 및 S파 속도가 감소하는 상관관계를 보였다. 완전파형음파검층을 통하여 얻어진 동탄성계수는 동체적탄성계수와 동전단탄성계수에 비하여 높은 값을 보인다.
