Deterioration determination device, deterioration determination method, and recording medium

A deterioration determination method comprising:

• acquiring a diagnosis result of first deterioration of a structure and a determination result of a displacement of a ground surface including the structure;
• determining second deterioration of the structure using the diagnosis result of the first deterioration and the determination result of a displacement of the ground surface;
• and
• outputting the second deterioration and a position of the second deterioration, wherein
• the diagnosis result of the first deterioration includes deterioration of a surface layer of the structure and a position of the deterioration,
• the determination result of the displacement of the ground surface includes a displacement of the ground surface including the structure and a position of the displacement, and
• the deterioration determination method further comprises:
• extracting a range in which a displacement included in the determination result of the displacement of the ground surface is larger than a displacement threshold value in the determination result of the displacement of the ground surface, and determining the second deterioration using the diagnosis result of the first deterioration and the determination result of the displacement of the ground surface included in the extracted range;
• or
• extracting a point at which a deterioration included in the diagnosis result of the first deterioration is larger than a deterioration threshold value in the diagnosis result of the first deterioration, and determining the second deterioration using the diagnosis result of the first deterioration and the determination result of the displacement of the ground surface at the extracted point.
