초록
Reclaimed land was mainly used as agricultural land for rice production. As a higher value-added business in the agriculture has recently been activated,green houses are being constructed. In case of green house construction on the reclaimed land, it is generally soft ground with high soil water content,so it is important to design the foundation for greenhouse construction. The object of this study, a pull-out test was conducted to derive the base linedata of the wooden pile foundation when constructing a green house. To reproduce the actual site, 30% of soil saturation and 70% of soil saturationwere created in the soil box. Groove number and depth were set as design factors of the wooden pile, and a pull-out test was conducted. As a resultof the test, pull resistance increased as the number of grooves increased, pull-out resistance according to groove depth was different according to soilsaturation. Also, after the experiment, we want to compare the set-up effects over time.
