| Summary: | Rock creep has a great influence on the stability of rock engineering, and water contentis an important factor affecting the properties of rock creep, but a large number of existing rockcreep models do not consider the effect of water content. Based on the Burgers model and theprinciple of damage mechanics, this paper proposes an improved Burgers model by introducing thecreep experience element which takes into account the water content, verifies the rationality ofthe proposed model by experimental data, carries out the secondary development of the proposedmodel by FLAC3D software, and analyzes the deformation trend of the Laoqingshan tunnel (as anexample) based on the proposed model. The results show that the larger the water content is, thesmaller the displacement of the crown after support and the tunnel floor occur. |
