A Study on the Geometric Deformation Measurement of Structures by Collinearity Condition
공선조건에 의한 구조물의 기하학적 변형해석에 관한 연구
Abstract
As for the deformation measurement of structure, there are many controversial points in using the methods by the strain guage, inclinometer, bial guage, and geodetic method because of the difficulty of instrument setting and the problem in the degree of accuracy of the results as well as in the economical aspect. Therefore, to verify the superiority of the Close- Range Photogrammetry method for the structural deformation measurement, the result of load deformation on the model structure, which was made using the Close-Range Photogrammetry method was compard with the results which was made using the methods of dial guage, precision level, and triangulation. In addition to that, to consider the general problem which would happen when C. R. P method was applied to the practical structure. The elements of C. R. P method like camera rotation angle (
구조물의 변형측정에 있어서 Strain gauge, Inclinometer, Dial gauge등을 이용한 방법과 측지학적인 방법들은 기구설치의 어려움과 경제적인 면은 물론 정확도면에서도 많은 문제점을 안고있다. 이에 최근 다방면으로 활용이 증대되고 있는 C. R. P(Close-Range Photogrammetry) 기법을 토목구조물의 변형측정에 적용하여 이를 공선조건으로 해석하였다. 피사체로 현수교모형을 제작하였으며 재하변형측정 실험을 실여, Dial gauge, Precision level, 정밀삼각측양을 통한 측정값과 비교하여 그의 타당성을 제시하였다. 또한 실구조물에 적용시 발생하는 제반문제점들을 고려하기위해 Camera 회전인자
