According to actual engineering of a highway neighborhood tunnel, The surrounding rock stress field monitoring of bench cut method has done and the field monitoring data has been compared with numerical simulation results. The result shows: The surrounding rock stress release with time in excavation, every construction step can effect the stress of surrounding rock and lining. The construction of...
The surrounding rock stress field monitoring of sequential mining method has done and the field monitoring data has been compared with numerical simulation results. The result shows: Surround rock stress changes violently when the distance from monitoring section to the lower bench is less than a tunnel diameter, when the distance is more than a tunnel diameter, the surround rock presents rheological...
According 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. The stress of the surrounding rock release with time...
