**4. Conclusions**

In this paper, the numerical simulation method is used to simulate the distribution characteristics of the smoke temperature field of a double-deck bridge during tanker fire under natural ventilation. The influence of bridge deck spacing on the smoke temperature field change is investigated. The following conclusions can be obtained:
