| Outline of Final Research Achievements |
In the present study, it was carried out research and development using the optical measurement technology.
①We have developed a monitoring device to observe the surface cracks, internal cracks, and crack repair material of RC structures. ②We carried out stress measurement of PC girder using the stress release method and confirmed the validity to the actual PC structure. In addition, we have developed a crack detection device by providing a thermal load. ③In order to evaluate the corrosion environment impact factor, the salinity of the concrete specimens that exposure I have continuously measured. In order to evaluate the corrosion environment impact factor, the salinity of exposure concrete specimens have been measured continuously. ④Using a three-dimensional laser scanner and unmanned air vehicle (UAV), we did the development of remote measurement system of deterioration damage of infrastructures.
