Stability and viscoelastic analysis about the surrounding rock of highway tunnel
2011 International Conference on Electric Technology and Civil Engineering (ICETCE), 2011According to actual engineering of a highway tunnel, this paper studies the tunnel stability without support and with support by Poynting-Thomson model. The transformation law of the stress with time of the bolt-shotcrete support is discussed. The results show that theoretical calculations and field monitoring data are in comparative agreement.
