However, in past earthquakes, there have been many road bridges damaged due to liquefaction of the ground, and it has taken a long time to restore them. As part of the Strategic Innovation Program (SIP), a large-scale shaking table test was conducted for road bridges in collaboration with the Public Works Research Institute in 2018. The aim of this experiment was to clarify the behavior of bridges during earthquakes and to verify a seismic reinforcement technique. Unreinforced and reinforced specimens were prepared, with the former simulating old road bridges that are at risk of being fatally damaged by liquefaction, and the latter simulating bridges that have been reinforced using a seismic reinforcement method that can be implemented while ensuring the flow of road traffic, and they were shaken using seismic motion as defined in the design standards. A series of experiments has provided useful data for clarifying the behavior of road bridges during earthquakes and verifying the reinforcement.", "subitem_description_language": "en", "subitem_description_type": "Abstract"}, {"subitem_description": "データ取得：2018年　", "subitem_description_language": "ja", "subitem_description_type": "Other"}, {"subitem_description": "Data acquisition period : 2018", "subitem_description_language": "en", "subitem_description_type": "Other"}, {"subitem_description": "お問い合わせ：asebi@bosai.go.jp　", "subitem_description_language": "ja", "subitem_description_type": "Other"}, {"subitem_description": "inquiry： asebi@bosai.go.jp", "subitem_description_language": "en", "subitem_description_type": "Other"}]}, "item_1617186643794": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_1522300295150": "ja", "subitem_1522300316516": "防災科学技術研究所"}, {"subitem_1522300295150": "en", "subitem_1522300316516": "National Research Institute for Earth Science and Disaster Resilience"}]}, "item_1617186660861": {"attribute_name": "Date", "attribute_value_mlt": [{"subitem_1522300695726": "Issued", "subitem_1522300722591": "2020"}]}, "item_1617186783814": {"attribute_name": "識別子", "attribute_value_mlt": [{"subitem_identifier_type": "DOI", "subitem_identifier_uri": "10.17598/NIED.0020-E201707"}]}, "item_1617258105262": {"attribute_name": "Resource Type", "attribute_value_mlt": [{"resourcetype": "dataset", "resourceuri": "http://purl.org/coar/resource_type/c_ddb1"}]}, "item_1617353299429": {"attribute_name": "関連情報", "attribute_value_mlt": [{"subitem_1522306207484": "isIdenticalTo", "subitem_1522306287251": {"subitem_1522306382014": "URI", "subitem_1522306436033": "https://asebi.bosai.go.jp/"}, "subitem_1523320863692": [{"subitem_1523320867455": "en", "subitem_1523320909613": "LOGIN Page for Registered Users"}]}]}, "item_title": "液状化地盤上の道路橋基礎の耐震補強技術に関する大規模実証実験", "item_type_id": "40006", "owner": "7", "path": ["1749778844647"], "permalink_uri": "https://nied-repo.bosai.go.jp/records/7221", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2025-06-19"}, "publish_date": "2025-06-19", "publish_status": "0", "recid": "7221", "relation": {}, "relation_version_is_last": true, "title": ["液状化地盤上の道路橋基礎の耐震補強技術に関する大規模実証実験"], "weko_shared_id": -1}
