DETERIORATION EVALUATION PROGRAM, DETERIORATION EVALUATION DEVICE, AND DETERIORATION EVALUATION METHOD
To evaluate the deterioration state of a bridge floor slab excluding the effect of temperature.SOLUTION: A deterioration evaluation device 1 acquires observation data including temperature information of an upper surface and a lower surface of a floor slab to be evaluated for deterioration evaluation and inclination information by a girder to be evaluated and an inclination sensor installed on the floor slab for a period in which the relation between the temperature of the upper surface and the temperature of the lower surface changes. The deterioration evaluation device 1 constructs a prediction model on the inclination angle of a single floor slab and the relation between the temperature of the upper surface and the temperature of the lower surface of the floor slab from observation data. The deterioration evaluation device 1 evaluates the deterioration of the floor slab using the prediction model.SELECTED DRAWING: Figure 1
【課題】橋梁の床版の劣化状況を、温度による影響を除外して、評価する。【解決手段】劣化評価装置１は、劣化を評価する評価対象の床版の上面および下面の温度情報と、評価対象の桁と床版に設置された傾斜センサによる傾斜情報とを含む観測データを、上面の温度および下面の温度との関係が変化するような期間分取得する。劣化評価装置１は、観測データから、床版の単体の傾斜角、並びに、床版の上面の温度および下面の温度の関係に関する予測モデルを構築する。劣化評価装置１は、予測モデルを用いて、床版の劣化を評価する。【選択図】図１
