건설공사시 환경공해진동의 평가를 위한 기초자료를 제공할 목적으로 댐 구조체가 가지고 있는 자유장에서의 고유진동수를 측정한 결과 A 측점 : 32.833 ㎐, B 측점 : 47.827 ㎐, C 측점 32.083 ㎐, D 측점 34.167 ㎐, E 측점 : 191.67 ㎐, F 측점 : 70.833 ㎐, G 측점 : 81.667, H 측점 : 31.042 ㎐, I 측점 : 19.250 ㎐, J 측점 : 95.833 ㎐, K 측점 : 29.425 ㎐, L 측점 : 26.833 ㎐로서 댐 구조물의 양 끝점에서는 비교적 저주파 영역으로 측정되었다. 특히 E, J 측점의 경우 주파수 영역의 편차가 크고, 랜덤하게 나타나는 이유는 바람의 영향, 수압, 그리고 댐 구조의 중앙 부위로 될수록 고유진동의 주기가 타 측점에 비하여 크기 때문으로 판단된다. 한편, 가속도의 경우도 고유주파수의 경향과 유사하게 나타나고 있음을 알 수 있다.
