Effects of Freeze-Thaw Circumstance on Stress and Displacement Filed of Tunnel Surrounding Rock

Abstract:

The stability of tunnel surrounding rock is a key scientific issue in the design and construction of the tunnel engineering. Taking the load pattern of incremental form, the distribution law of stress and displacement field of the Osaka mountain tunnel after excavation was calculated based on the D-P yield criterion; Basing on the comprehensive heat and mass transfer theory, the temperature field in the surrounding rock was calculated and the variation of stress and displacement field after the surrounding rock experiencing the free-thaw cycles. All of the results can provide some references for the design and safe construction of the tunnel engineering under the action of freeze-thaw environment in cold regions.
