Tunnel Supporting Structure Stress and Displacement Characteristics Research

Abstract:

Taking dual carriageway standard cross section given by the current highway tunnel design standard and supporting structure parameters of surrounding rock in V class for example, using ADINA large deformation nonlinear finite element software, this paper divides the supporting structure into small units, and analysis the stress and displacement characteristics in different position of five typical sections in the tunnel construction process. Analysis results show that displacement and stress-time change feature is different apparently between inner and outer side of supporting structure, and also at different sections; displacement at inner and outer side of the same section is similar, while there is considerable difference in different sections; stress at inside and outside of one section is obviously different with that of other sections, which provides scientific basis for the safety of tunnel support structure and the optimized design.
