| description | Provided is a method for detecting damage to a deck of a bridge, the method allowing detection work to be achieved with less labor and being capable of reducing the time and cost needed for the detection work. From a road-surface measuring vehicle running on pavement 3 on top of a steel-plate deck 1, a thermal infrared video of the surface of the pavement 3 is acquired by a thermal infrared video camera. Based on the thermal infrared video, troughs 4 of the steel-plate deck 1 are detected to grasp the structure of the steel-plate deck 1. Residence of water inside prescribed trough members 41 and sealing diaphragms 42 is detected from low-temperature regions R2 from among regions corresponding to troughs 4 in the thermal infrared video, and from rectangular low-temperature sections L2 that surround the regions R2. Through cracks are detected in deck plates 2 that correspond to troughs 4 in which residence of water has been detected. |
