Abstract:As a new type of geosynthetics,geotextile is gradually infiltrated into building foundation,road(railway)subgrade and other projects.On the basis of previous studies,this paper summarizes the numerical simulation of geobags based on Abaqus commercial finite element software from five aspects:the introduction of simulation software,soil constitutive model, bag element, contact analysis and example calculation.The feasibility of the selected constitutive model,element and contact is verified by unconfined compression test and horizontal shear test.
