Numerical Simulation of Shear Property of Geosynethtics and Soil Interface

Tensile test calculation mode for geosynethetics is established based on finite element method to analyze mechanical behavior of reinforced soil interface,study the distribution of reinforced soil interface friction and reinforced material tensile deformation under different displacement of tensile end,and study the influence of reinforced material rigidity and test overload on reinforced soil interface friction and reinforced material tensile deformation.It is indicated that reinforced soil interface friction is not distributed uniformly,but the interface frictional resistance has a peak value near tensile end.For high-strength reinforced material,with the increase of displacement of tensile end,peak friction gradually moves backward till the whole interface slides under shear strength.Reinforced material tensile rigidity shall be compatible with overload.The more overload,the higher rigidity and the stronger bearing capacity of reinforced material.
