Abstract

Malpasset Dam, located in France, is of great importance in the field of civil and geotechnical engineering as it was the first arch dam that totally collapsed in 1959. A three-dimensional model of the dam was reconstructed using close-range photogrammetry technique. The orientations of foliation developed in the bedrock and the collapse surface were measured. Moreover, both model and measurement results showed high precision. The study result can be used in future studies such as collapse simulation analysis and geotechnical investigations.

프랑스에 있는 Malpasset Dam은 1959년에 일어난 아치댐의 첫 번째 붕괴사례로 토목, 지반 및 지질공학적으로 중요한 의미를 가진다. 근거리 사진 측량 기법을 이용하여 댐의 3차원 재구성 모델을 만들었으며 모델을 통해 댐의 붕괴 형상을 관찰하고 붕괴면의 수치측정 및 기반암에 발달한 엽리면의 배향을 측정하였다. 모델과 측정결과 모두 높은 정확도를 보여주었으며, 이 연구의 결과물은 추후 붕괴시뮬레이션 해석 및 지질공학조사 등에 활용할 수 있다.
