In　this　study,　temperature　monitoring　and　freezing　disaster　investigation　in　winter　were　conducted　in　three　high　latitude　cold　regional　tunnels　of　Northeast　China.　Observations　indicate　that　the　air　temperature　in　the　tunnel　middle　section　and　the　deep　buried　central　drainage　pipe　remains　stable　at　0-5　degrees　C,　while　at　the　entrance　section　and　the　side　ditch,　it　fluctuates　around　-15　degrees　C　for　about　2　months.　Consequently,　warm　water　from　the　middle　section　supplies　both　ends　of　the　tunnel,　making　the　entrance　section　drainage　system　prone　to　ice　jams　and　freezing　damage.　Field　investigation　reveals　5　types　of　freezing-induced　catastrophic　behavior　in　tunnel　drainage　systems.　In　addition,　frost　heave　effects　from　drainage　system　failure　are　simulated,　showing　that　the　lining　compressive　stress　due　to　frost　heave　of　drainage　system　is　about　450　kPa,　which　is　200%　of　the　surrounding　rock　frost　heave.　Moreover,　the　tensile　stress　due　to　frost　heave　of　the　side　wall　crack　seepage　or　cavity　water　is　the　most　significant,　followed　by　the　arch　springing,　then　the　hance,　and　finally　the　vault.　Finally,　consideration　of　the　frost　heave　effect　induced　by　drainage　system　is　crucial　for　ensuring　tunnel　operation　safety　in　high　latitude　cold　regions.
