Study on visualization simulation of temperature distributions in surrounding rock of tunnels in a deep mine

摘要

Based on the mathematical model for rock temperature distribution in a geo-thermal field, the properties of rock temperature distribution in geothermal field for four kinds of surrounding rock cross-sections of tunnels in a deep mine were simulated by using finite element method. It is shown that the relationship for rock temperature distribution varied with the geothermai parameters, time and space. Namely, 2-dimensional time-dependent isograms clearly showed the process for rock temperature variation and distribution in a geothermai field which has been redisplayed with visualization numerical simulation.
