Abstract

In this study, a field test of uplift load was carried out using 15 greenhouse foundations fabricated in full scale on a sand soil to examine the uplift capacity of plastic film greenhouse and glasshouse foundations for disasterproof standard. As a result, the maximum uplift capacity of the target greenhouse foundations was shown to be in the range from 11.6kN to 82.4kN according to the differences between the forms and sizes of the foundation. As a result of the examination of the applicability using the field uplift load test result of the theoretical equation proposed for maximum uplift capacity calculation of greenhouse foundations, we found that in general, the conventional theoretical equation for the calculation provided numerical values close to the field test results. However, the soil considered in this study was a sand; thus, in the future, verifying the conventional theoretical equation for the uplift capacity calculation of a cohesive soil would be necessary.

본 연구에서는 내재해형 플라스틱 온실과 유리온실의 기초에 대하여 인발저항력을 검토하기 위해 사질토 지반에서 실규모로 제작한 총 15개의 온실 기초를 이용하여 현장시험을 실시하였다. 그 결과, 대상 온실 기초의 최대인발저항력은 기초의 형태 및 규모가 서로 상이함에 따라 11.6 kN~82.4kN의 범위로 나타났다. 온실기초의 최대인발저항력 산정을 위해 제안된 이론식에 대하여 현장시험 결과를 이용하여 적용성을 검토한 결과 전반적으로 기존의 산정 이론식이 현장시험결과와 근접하는 수치를 제공하는 것으로 검토되었다. 다만, 본 연구에서 고려한 지반은 사질토 지반이며, 향후 점성토지반에 대하여 기존의 인발저항력 산정 이론식의 검증이 필요할 것으로 판단된다.
