Time–dependent rock behaviour in tunnelling
(2011) European Conference on Soil Mechanics and Geotechnical Engineering p.1615-1620- Abstract
- The rock mass viscous behaviour during tunnel construction is discussed. Initially, a brief introduction to the squeezing phenomenon and its association with the related one of creep is provided. Then, existing simplified models of rheological rock mass behaviour are presented and analysed. The range of the viscoelastic rock parameters identified in the literature for weak rocks is also given and results obtained from existing viscoelastic closed form solutions for tunnelling, are compared to numerical results. Finally, numerical simulation using a combined viscoelastic–plastic model is presented.
