Abstract
In Shizuoka Airport Construction Project a high filling (21m high) is obliged to protect a kind of precious plant (Tashiroran in Japanese Name), so we applied the fill reinforced by geosynthetics. During filling we observed the behavior of the fill (settlement, horizontal displacement, eath pressure, pore water pressure, strain of geosynthetics). From the resuruts of above mentioned field observations it is clear the fill is a sense of stability. This paper describes fill construction and the resuruts of field observations.
