Study On Rapid Construction Technology And Support System Of High Altitude Seasonal Frozen Soil Tunnel

In this paper,a high control engineering of birchbark Ridge Tunnel,tunnel construction technology of fast and security system.Aiming at the bad construction disease birchbark Ridge Tunnel implementation,the bias tunnel hole fast and adverse conditions in treatment plan;to ensure the different construction methods of rapid hole shallow buried soft rock tunnel,using FLAC3 D numerical analysis software to optimize and select;to further ensure the quality of construction safety of the tunnel,the tunnel construction in winter heating the heating quality safeguard measures,and by using fluid mechanics software Fluent,analyzes the tunnel construction in winter temperature field,velocity field distribution,optimization of technical measures at the end of the warm air;tunnel construction process control of the tunnel design and comprehensive application of straight shift mode research,discussion and improvement.The results obtained in this paper will be of some reference value for the rapid construction of high altitude seasonal frozen soil tunnel and the establishment of its support system.
