The Research Of Simulation About Anchor And Lattice Frame

The landslide is a frequent disaster in China, it often demage the safety of life andproperty, anchor and lattice frame is a way to reinforce the slope which uses more and morefrequently in recent years, but the research of anchor and lattice frame how to interact eachother on the slope is relatively backward, limiting it’s application.The article is based on the China Geological Survey Project " Large Physical Model Teston lattice and anchor frame for landslide "（The number is1212011220145）which focus onthe deformation and destruction about anchor and lattice frame in the application of landslideprevention. The main research contents and results are as follows:（1）Doing landslide model test respectively, which are landslide basic parameters inphysical model test and large scale physical model test,obtaining a large amount of test data.（2）Based on the physical model, then doing finite element numerical simulation,obtained the displacement distribution, stress distribution and the slope failure mode indifferent kinds of loading conditions. The article focus on the mechanical laws of cableelement and lattice beam element.（3）Through the analysis of the data about the simulated experiment, obtained thecables’ force and beams’ bending moment in different loading conditions. Finally, based onthe distribution of soil behind beams, putting forward the calculation of subgrade reaction.
