Abstract

Abstract

During tunnel excavation,geologists should give the geological prediction based on the geological conditions of tunnel,and propose engineering support methods to ensure the safety of tunnel construction.Comparative analysis of stereographic projection and Unwedgeis conducted in the same tunnel for the stability analysis of rockmass.The comparative analysis shows that Unwedge has advantages of better visualization,more convenience for operation,etc.The application of Unwedgeis expected to be promoted in geological construction during tunnel excavation.
