Abstract


The thesis systemically analyzes the current working performance ofthe shallow buried road tunnel and the upper vertical crossing structure athome and abroad , and the influences on tunnel surrounding rock andtunnel lining on the condition of the tunnel suffering from the uppertraffic loading are systematically researched by theoretical analysis,model test analysis and numerical simulation analysis.1) Basing on the current road and the shallow buried road tunnel andthe upper vertical crossing structure .The model test proposal isestablished and research is executed on the similarity theory2) Tunnel calculating model is established by using the software offinite element analysis and adopting the elastoplastic analytical methodand the Mohr-Coulomb yield criterion, make the two-dimensionalnumerical simulation to get the wall rock and the tunnel liningdisplacement and strain ,getting the change law of the stress and strain .3) Evaluating the stability and the safety of the wall rock and thetunnel lining by the contrastive analysis of the model experimental dataand finite element numerical simulation result. If the model experimentaldata and finite numerical simulation are close ,it means the rationality ofthe method and the parametric model and responses the stress and straincharacteristic under the road traffic of tunnel. At the same time ,it canimprove the theory basis of the shallow buried tunnel design , the safetimbering and maintenance under the condition of the tunnel and theupper vertical crossing structure.
