As a result, the\nriverbed soft rocks have been eroded resulting from slaking and the level of the river bottom\nis getting lower. This is the cause of problems such as damage to river banks and difficulties\nin agricultural water intake. In this study, we measure the slaking depth on the soft rock\nsurface happened as a consequence of repetitive drying and water immersion using soft rock\nsamples collected in this area. The results are as follows. One cycle of dry/wet repetition\nmake about 3 mm of granulation on the soft rock surface. The thickness of this granulation\nbecome smaller if sufficient drying conditions are not provided. Remaining particles on the\nsoft rock surfaces after slaking seem to delay granulation. The soil classification of\ndisintegrated particles is also shown.","subitem_description_type":"Abstract"}]},"item_3_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11225201","subitem_source_identifier_type":"NCID"}]},"item_3_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1343-8867","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"土倉, 泰"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2022-03-23"}],"displaytype":"detail","filename":"24-01.pdf","filesize":[{"value":"603.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"24-01","url":"https://maebashi-it.repo.nii.ac.jp/record/415/files/24-01.pdf"},"version_id":"2c46d312-5aa2-4326-8767-c76c6fa74c39"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"河床浸食"},{"subitem_subject":"軟岩"},{"subitem_subject":"スレーキング"},{"subitem_subject":"Stream bed erosion","subitem_subject_language":"en"},{"subitem_subject":"Soft rock","subitem_subject_language":"en"},{"subitem_subject":"Slaking","subitem_subject_language":"en"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_title":"碓井川河床軟岩を対象とした乾湿繰り返しによる細粒化の実験","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"碓井川河床軟岩を対象とした乾湿繰り返しによる細粒化の実験"},{"subitem_title":"Laboratory measurements of the slaking depth on the surface of soft rocks sampled at the Usui River","subitem_title_language":"en"}]},"item_type_id":"3","owner":"4","path":["36"],"pubdate":{"attribute_name":"公開日","attribute_value":"2022-03-23"},"publish_date":"2022-03-23","publish_status":"0","recid":"415","relation_version_is_last":true,"title":["碓井川河床軟岩を対象とした乾湿繰り返しによる細粒化の実験"],"weko_creator_id":"4","weko_shared_id":-1},"updated":"2023-06-20T14:10:05.656391+00:00"}
