Abstract：The law of ground pressure during roadway tunneling under shallow burial conditions is complex,and the stability control of the surrounding rock during tunneling under wind oxidation zones,seasonal rivers,and roads is more difficult.In order to better understand the deformation and failure laws of the surrounding rock during roadway tunneling under complex conditions of shallow burial depth,the Protodyakonov equilibrium arch theory and numerical simulation were used to ana-lyze and study the deformation and failure laws of the surrounding rock after roadway tunneling.The research results show that the top and bottom of the roadway are within the top influence range of the pressure relief zone,which is less than 30 meters.The tunneling of roads under wind oxidation zones,seasonal rivers,and roads does not affect the ground and can meet the safety requirements for roadway tunneling construction.The research results can provide a basis for the rational layout of roads under similar conditions.
