Abstract

This paper presents the application of the Coupled Eulerian-Lagrangian (CEL) technique to simulate the debris flow. The main objective of this study is to investigate the applicability of CEL technique to the behavior of debris flow, such as flow velocity and influence area. Comprehensive studies to verify the behavior of debris flow are presented in this study. Through comparison with measured flow velocity from Umyeonsan (Mt.), CEL approach was found to be in good agreement with the general trend observed by in actual debris flow. In addition, CEL technique accurately simulated the behavior of debris flows, therefore, it can be used for designing the countermeasure structure.

본 연구에서는 토석류의 유하부 도달 속도 및 피해 영향범위 등의 흐름 특성을 파악하기 위하여 대변형 3차원 유한요소 해석을 수행하였다. 대변형 해석은 ABAQUS (Ver 6.13, 2013)의 Coupled Eulerian-Lagrangian (CEL) 기법을 이용하였으며, 실제 토석류 발생 지역의 관측 값과 해석 결과를 비교함으로써 CEL 대변형 해석기법의 타당성을 검증하였다. 그 결과, CEL 대변형 해석기법은 토석류 거동을 합리적으로 예측 할 수 있음을 확인하였다. 또한 토석류의 흐름에 사방댐이 미치는 영향을 확인하기 위하여 추가적인 해석을 수행하여 분석하였다. 그 결과, 사방댐에 의해 유하부로 흘러 내려오는 토석류의 속도와 체적의 감소효과를 확인하였고 토석류에 의해 발생하는 충격력을 산정하였다. 이로 인하여 대변형 토석류 해석기법은 기존 사방댐 안정성 평가 및 사방댐 설계에 활용이 가능할 것으로 판단된다.
