경계면 요소를 이용한 기초거동에 관한 수치해석 = A Numerical Analysis of Footing Behavior using Interface Element

다국어 초록 (Multilingual Abstract)

This research is an numerical study of investigating effects of base roughness of strip footing in sandy foundation on load-settlement characteristics, ultimate bearing capacity, and failure mechanism. For model foundation, Jumunjin Standard Sand was used and prepared in the specially built model container to simulate loading conditions of the strip footing in field. Parametric experiments under plane strain conditions were performed by changing properties of interface between foundation and footing such as placing vinyl, aluminum, sand paper, and sand itself beneath the model footing. Relative densities of sandy foundation was also changed during tests. Ultimate values obtained from tests were compared with estimated values by using limit equilibrium methods. The load-settlement behavior of footing obtained from tests was also compared with results from using a numerical technique of Finite Element Method with hyperbolic constitutive relation.
