【Abstract】 Due to the excellent engineering performanc e of the geo-grid, it is o ften used as reinforcing material for reinforced soil structure. In this paper, the main factors influencing the pull out test are analyzed, such as loading man ner, edge effect and size effect of the side wall of the pullout box, thickness of the filling material, degree of compaction and holding of reinforcing materia l in order to properly carry out the pullout test and analyze the mechanism of i nteraction between geo-grid and the filling material.更多还原
