| Zusammenfassung: | To provide an evaluation method and an evaluation system for evaluating soundness of a bridge pier capable of reducing labor work and cost for maintenance management of a bridge pier foundation for a river and the like.SOLUTION: An evaluation method for evaluating soundness of a bridge pier comprises the steps of: measuring response displacement of an upper surface of the bridge pier when a train passes thereon; calculating a limit value of sound displacement based on structural design specifications of the bridge pier; and determining the soundness through comparison between a measured value of the response displacement and the limit value.SELECTED DRAWING: Figure 4
【課題】河川等の橋りょうの橋脚基礎の維持管理において、手間やコストを抑制して健全度を評価する評価方法および評価システムを提供する。【解決手段】橋りょうの橋脚の健全度を評価する方法であって、列車通過時において橋脚の天端の応答変位を測定する工程と、橋脚の構造諸元に基づいて、健全な変位の限界値を算出する工程と、応答変位の測定値と限界値とを比較し、健全度を判定する工程と、を有する。【選択図】図４ |
