A Study on Temperature Distribution of Surrounding Rock and Mechanical Characteristics of Lining of Monglian Tunnel under High Geothermal
To solve design and construction problems of Monglian tunnel under high geothermal, based on the change rules of thermal parameters of surrounding rock and lining during excavation period, this paper analyzed the temperature distribution, heat transfer in tunnel and interaction between lining and surrounding rock, then by using numerical simulation, the relationship between temperature field and mechanical characteristics of lining and surrounding rock was discussed. Finally, the methods of using blast furnace cement, utilizing wet spraying concrete construction technology, and making surrounding rock exposure time as short as possible to reduce damages high temperature caused was proposed. The result can provide experience in similar tunnel design and construction.
