Based on Ansys the Deep Rock Tunnel Thermal-Mechanical Simulation
With deep coal mining mining and deep geothermal resource development.The threat of high temperature hazards is growing increasingly severe,therefore,carried out thermal mechanical coupling of deep tunnel under high-temperature conditions has a very important practical significance.In this paper.based on the mechanism of thermal-mechanical coupling, we conduct thermal-mechanical coupling numerical simulation of the deep tunnel.the results from temperature contour figure, temperature contour is symmetric and gradually spread out around the tunnel;thermal-stress generated by temperature change has a great impact on deep tunnel,in the deep tunnel of high temperature thermal-stress should be considered.thermal-mechanical coupling of the maximum stress appears in the tunnel near the two corner.the higher the temperature the stress becomes larger.the maximum percentage of stress increase is up to 9％.
