축소모형에 의한 싱크-홀 보강슬래브의 실험적 성능평가

Abstract

Sink-hole is a kind of ground settlements caused by collapse of the underground space when the important structure is constructed on the closed mine tunnel. Thus Sink-hole must be reinforced certainly. Therefore, in this study, experimental performance evaluation of Sink-hole-reinforcing slab is done by scaled model. In this time, rock and silt which is selected by soil condition, are used as ground model which scale is same ratio as reinforced slab. This experiment estimate through the stability of reinforced slab and the ground mutual behavior analysis.
