Analysis of Soft Rock Tunnel Mechanics Effects Based on Strain Softening Model of Surrounding Rock
Aiming at mechanical response of soft surrounding tunnel affected by high stress, the mechanical effect in the process of excavation and supporting of surrounding rockmass was analyzed by softening model. First of all, mechanics properties of soft surrounding rock and strain softening model have been discussed. Then, based on strain softening model, numerical analysis was carried out, and stress and displacement field, plastic range in the in the process of excavation and supporting was obtained. The result was very useful for the optimization of construction design and perfection for supporting program.
