초록

In this study using the finite different programs, FLAC2D to define affection of the soil-structure interface in evaluating the behavior of adjacent structures according to excavation, and tried to compare each the results of different 46 cases which were various condition of stories, length and locations from the excavation site. In the result of the numerical analysis, the affection of the interface was affected by the building stories, locations from the excavation site and shape ratio(length/height). Therefore, in the considering soil-structure interaction in the damage assessment and the behavior of the adjacent structures when excavation, is important in more accurate evaluation of the movement of structure. Also, the interface modification factor were proposed which can consider the interface.
