In particular, Hyogo Prefecture has the largest number of reservoirs in Japan, with around 38,000. In the past, repairs have been carried out using the “Hagane-do” method, which uses impermeable soil layer to prevent water from seeping through. In cases where this method is difficult to apply, there has been an increase in the number of cases using a bentonite impermeable sheet method. However, since it is not yet clear if they can maintain their water-proofing and durability after an earthquake, a shaking table experiment using a full-scale model was conducted as collaborative research with Hyogo Prefecture and Kobe University to compare the Hagane-do method and the impermeable sheet method. As a result of the experiment, cracks appeared on the top of the embankment in the impermeable sheet method. However, as there was no leakage or collapse after the seismic motion, it was found that the impermeable sheet itself maintained its function.", "subitem_description_language": "en", "subitem_description_type": "Abstract"}, {"subitem_description": "データ取得：2016年　", "subitem_description_language": "ja", "subitem_description_type": "Other"}, {"subitem_description": "Data acquisition period : 2016", "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": "2018"}]}, "item_1617186783814": {"attribute_name": "識別子", "attribute_value_mlt": [{"subitem_identifier_type": "DOI", "subitem_identifier_uri": "10.17598/NIED.0020-E201511"}]}, "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": "ため池堤体 -遮水シート工法の耐震性確認実験-", "item_type_id": "40006", "owner": "7", "path": ["1749778844647"], "permalink_uri": "https://nied-repo.bosai.go.jp/records/7213", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2025-06-19"}, "publish_date": "2025-06-19", "publish_status": "0", "recid": "7213", "relation": {}, "relation_version_is_last": true, "title": ["ため池堤体 -遮水シート工法の耐震性確認実験-"], "weko_shared_id": -1}
