Abstract
A visual experimental system was developed to investigate the interaction mechanism of underground granary embedded in sandy soil considering the rising of groundwater level. The results show that the buoyancyinduced failure process of the granary-soil system can be divided into two stages: floating and instability failure (or tilting). Higher soil relative compactness enhances embedding capacity and deformation resistance, significantly improving system stability when exceeding 0.501. The retaining wall earth pressure theory explains their interaction, and granary tilting is caused by soil shear-slip-induced stress deviation. This study provides support for promoting underground granary popularization in groundwater-rich areas.
