The temperature data at each section of the middle span of Cangkou cablestayed bridge were extracted through the long-term monitoring system on the Jiaozhou Bay Bridge which located in north China sea to establish the probability distribution model. Combined with relevant domestic and international standards, the temperature reference value calculation method based on extreme value analysis was discussed, and the recurrence and recurrence interval value of extreme temperature were analyzed. Results show that the recurrence interval value of extreme temperature is concerned with the original sample distribution function and sample volume. The difference between maximum and minimum value of the same measuring point in the 50 year recurrence period can be about 65℃ with a sample size 12. The result can provide a basis for section design of steel box girder and further research on influence of temperature stress.
