道路橋基礎の地震時挙動の評価と耐震対策技術の開発

摘要

We conduct research and development to achieve realistic evaluation of the seismic benavior and the resistance and deformation capacity of bridge foundations. In this report, we present the latest information on the current efforts by the Public Works Research Institute to improve the evaluation of the seismic behavior of bridge foundations built on liquefiable ground and to implement seismic retrofitting for such structures, as well as to upgrade the evaluation of seismic limit state of existing bridge foundations.%本稿では、より実際に近い基礎の地震時挙動、より実際に近い基礎の耐力•変形特性を評価できるようにしていくため、現在、土木研究所で取り組んでいる液状化地盤における基礎の地震時挙動の評価の高度化と耐震対策に向けた取組み、既設基礎の地震時限界状態の評価の高度化に向けた取組みの最新情報を紹介する。
