To Verify The Finite Element Model Of The Pinus Tabulaeformis Root-Soil Composite Based On The ANSYS

In recent years, Because of serious soil and water loss So people pay more and more attention to the study of root soil reinforcement mechanism. The mechanism of root system on soil reinforcement in the experimental research deeply and in the finite element method is still in the exploratory stage. In order to better study the finite element method is applied to the solid roots and soil mechanics mechanism of, This reference to Liu Xiaoguang, the root of pull-out test of single group.The establishment of the geometric model of root soil, The finite element model of root soil composite application of ANSYS, it consists of roots, soil and the contact interface is composed of three parts.Simulation of single and group roots from the soil in the process of pulling out,By the test data comparison and analysis results of finite element analysis,To verify the feasibility of the finite element model is established considering the interface unit, The specific contents are as follows:Through the comparison of single and group according to the results of finite element analysis with the results of pullout tests, Verify that the finite element model of root soil composite which consider interface unit in this paper has certain feasibility, Provides a model based on the root and soil mechanics for the further application of the finite element analysis.
