| Abstract: | A method for continuously monitoring the surface temperature of bridge structure was proposed by using the infrared thermography technology.The surface thermal field is established and the effects of various factors on the surface temperature were analyzed.The method provided comprehensive data for evaluating the effects of environmental factors on the temperature fields of the concrete structure,the mechanism of temperature effects on the thermal stress,and the risks of thermally induced concrete defects. |
