            Abstract: Combined with the example of Qilian Mountain tunnel leakage and freezing damage treatment in Ganqing section of Lanzhou to Xinjiang passenger dedicated line, this paper analyzes the causes of leakage and freezing damage in detail, and summarizes a complete set of treatment technology for leakage and freezing damage of high speed railway tunnel in plateau cold area through a lot of practice and attempts. That is to say, the new idea and technology of systematic comprehensive treatment such as water interception, water blocking, drainage, waterproof, heat preservation, heating and maintenance are adopted and applied to the treatment of leakage and frost damage of Qilian Mountain tunnel group, and good results have been achieved.
