| Abstract: | The model for calculation of the 3D transient temperature and irradiative flux of a bridge, with comprehensive consideration of the influence of sun, air, river, vehicle and so on, has been developed. Simulation of the infrared signatures of a bridge is also carried out using the finite difference method for the widely used concrete box girder bridge. |

| Keywords: | temperature field irradiative flux simulation of the infrared signatures |
