Proposed method for simple deterioration diagnosis of existing fishing port

Existing fishing port facilities form a huge stock for which deterioration diagnosis and repair constructions have started throughout Japan. Hence a simple and precise method for the deterioration diagnosis is needed. This study aimed to develop simple deterioration diagnosis method applicable to the fishing port facilities and a proposed method using impactecho was extensively tested through the inspection of existing structures. The results provided a quantitative measure for the immediacy of countermeasures, prediction of the timing of follow-up inspection and a simple deterioration diagnosis method. Availability of the proposed method was confirmed through the tests at existing fishing port facilities.
