Description
Technical field
This utility model relates to tunnel operating environment security technology area, particularly relates to the assay device of a kind of tunnel in cold area country rock and distinguished and admirable heat transfer. For studying the country rock temperature field law of development of tunnel in cold area and different draft type to tunnel in cold area temperature profile effect rule, it may be achieved to the measurement in temperature field in country rock and tunnel.
Background technology
In recent years, with the fast development of Chinese national economy, railway, highway construction are also at high-speed development period. Fast development along with China's communication; particularly Midwest great development and the further of rejuvenating the northeast economic policy are implemented; substantial amounts of tunnel will be had successively to build up at midwestern High aititude and northern high latitude cold district; compared with the tunnel of conventional cold district; the scale in these tunnels can bigger, technology require higher, and weather conditions are more severe.
According to studying report both at home and abroad, the adverse effect of Tunnel Engineering is had by common extremely frigid zones: freeze injury, and main manifestations is that icicle is hung on top, hole, abutment wall hangs ice and freezes to death in ditch, affects traffic safety; Frost causes various frost heaves, and ice melts change and causes the air slaking of lining concrete surface serious repeatedly, and vault ftractures, and the long-term stability of tunnel lining structure is constituted potential threat. Such as, up to now, in multiple tunnels that China northeast and northwest are built, due to freeze injury, having the time of a lot of tunnel half a year nearly not use, some is scrapped completely. The statistics that Japan Highway work is rolled into a ball and Japanese railway comprehensive technology research institute is nearest shows, has 1100 because of freeze injury reason, injure traffic safety in the winter time during operation in Japan's 3800 railway tunnel in the whole nation; In vcehicular tunnel, what serious cold damage only occurred in 302 large-scale vcehicular tunnels in area, Hokkaido just reaches 104, for eliminating side walls ice and arch icicle, as one of management measure, being provided with electric heater unit at relatively Multiple tunnel, the regulation expense of input is very surprising.Therefore, tunnel resists antifreeze problem to become the significant technology issues faced both at home and abroad.
For the anti-antifreeze problem in high and cold tunnel, big quantity research and experiment are carried out both at home and abroad. Its research is concentrated mainly on the classification of frost heave and mechanism of production, frost-heave force to aspects such as the impact of liner structure and prevention of frost heave measures. But up to now, effectively not solving tunnel in cold area freeze injury problem, the not good phenomenon of long-term antifreezing effect is especially prominent. Therefore the freeze injury controlling tunnel in cold area is had great importance by tunnel in cold area temperature profile effect rule by the cold country rock temperature field law of development of research and ventilation.
In tunnel in cold area research, owing to case history is less, achievement in research is few, and concentrate on the research to tunnel in cold area frost heave, study tunnel in cold area frost-heave force such as Lai Yuanming (1999) etc. and obtain viscoelastic analytical expresses, Yang Gengshe (2002) etc. sets forth elastic theory and Theory of Viscoelasticity country rock frost-heave force Analytic Calculation Method on the basis of certain hypothesis, Wang Jianyu, Hu Yuanfang (2004) have studied tunnel-liner frost-heaving force problem, LuX(2006), et al. Prashantk(2009) principle of stacking and the separation of variable is utilized to obtain consideration temperature with the analytic solutions of circular cross section transient state temperature field under the convection boundary condition of changes in coordinates. testing economy and facility based on small-scale model, more existing research worker have carried out multi-form tunnel in cold area model test both at home and abroad. such as, canal Meng Fei (2015) etc. sets up indoor model and tunnel in cold area lining cutting frost-heave force is studied, and cold district fragmented rock body tunnel frost-heave force is carried out indoor comparative test by the enemy Culture Revolution, Sun Bing (2010).
By some data are investigated, research method for tunnel in cold area temperature field includes field monitoring, theoretical research and model test three kinds, current research is concentrated mainly on field monitoring and theoretical research two aspect, and this research on the one hand of model test is still not enough.
Utility model content
For in above-mentioned prior art, field monitoring, theoretical research and model test three kinds are included for the research method in tunnel in cold area temperature field, current research is concentrated mainly on field monitoring and theoretical research two aspect, and this research on the one hand of model test is still not enough problem, this utility model provides the assay device of a kind of tunnel in cold area country rock and distinguished and admirable heat transfer.
