초록
A sub-structure is uplift if the floating greater than dead load of a structure. When such occasion arise, a structure sustain damage. In general, the measures for floating prevention of structure are a permanent anchor method and a drainage method. The primary construction cost of a permanent anchor method is heavy. And a drainage method is needed maintenance management long term. At this point, the measures for floating prevention of a notion being requires the other days. Therefore, at this study a simple construction and a economic vertical drainage system was developed. The findings be used in the in-situ and gave careful consideration to an application. The result of examination, this system considering a characteristic of coefficient of permeability for the ground controls occurrence of floating despite the water level rise of the ground, which a period of construction get shorter compared with other methods, which understood that measures satisfactory in the financial aspect. Especially, A structure occurring effects of flatting under the course of construction made use of it. As the result of the effect of it was confirmed by construction.
