Title (EN) MANAGEMENT METHOD AND MANAGEMENT DEVICE
(FR) PROCÉDÉ DE GESTION ET DISPOSITIF DE GESTION
(JA) 管理方法及び管理装置
Abstract:
(EN) Disclosed is an management method for managing a PC stranded wire with an optical fiber comprising: a PC steel stranded wire formed by twisting a plurality of PC steel strands; and an optical fiber arranged along the twists in the PC steel stranded wire. This management method is provided with a step for measuring propagation loss of scattered light from light incident on the optical fiber and a step for detecting abnormalities in the PC steel stranded wire with an optical fiber on the basis of the propagation loss measured in the step for measuring propagation loss.
(FR) La présente invention concerne un procédé de gestion pour gérer un fil toronné de précontrainte (PC) avec une fibre optique comprenant : un fil toronné d’acier PC formé par torsion d’une pluralité de torons d’acier PC ; et une fibre optique agencée le long des torsions dans le fil toronné d’acier PC. Ce procédé de gestion est pourvu d’une étape de mesure de perte de propagation de lumière diffusée par rapport à la lumière incidente sur la fibre optique et d’une étape de détection d’anomalies dans le fil toronné d’acier PC avec une fibre optique sur la base de la perte de propagation mesurée dans l’étape de mesure de perte de propagation.
(JA) 複数のPC鋼素線が撚られて形成されたPC鋼撚線と、PC鋼撚線の撚り目に沿って設置された光ファイバと、を有する光ファイバ付PC撚線を管理する管理方法を開示する。この管理方法は、光ファイバに入射させた光の散乱光の伝送ロスを計測するステップと、伝送ロスを計測するステップで計測した伝送ロスに基づいて光ファイバ付PC鋼撚線の異常を検知するステップと、を備える。
