The moisture content of soil that has frozen is high, whereas the moisture content of non-frozen soil below that is low, because water is drawn upward toward the soil that has frozen. If high-moisture soil can be improved to yield low-moisture soil using this phenomenon, low-cost improvement will be possible. Moisture can be reduced by repeated freezing and thawing, changes in soil temperature, then, soil moisture change through winter were monitored in outdoor experiments. It was shown that unsuitable soil could be improved by repeated freezing and thawing, that the decrease in moisture content was finished within one season.","subitem_description_type":"Abstract"}]},"item_3_full_name_183":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"42699","nameIdentifierScheme":"WEKO"}],"names":[{"name":"SATO, Atsuko","nameLang":"en"}]},{"nameIdentifiers":[{"nameIdentifier":"42700","nameIdentifierScheme":"WEKO"}],"names":[{"name":"NAKAMURA, Dai","nameLang":"en"}]},{"nameIdentifiers":[{"nameIdentifier":"42701","nameIdentifierScheme":"WEKO"}],"names":[{"name":"SUZUKI, Teruyuki","nameLang":"en"}]},{"nameIdentifiers":[{"nameIdentifier":"42702","nameIdentifierScheme":"WEKO"}],"names":[{"name":"NISHIMOTO, Satoshi","nameLang":"en"}]}]},"item_3_publisher_212":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"公益社団法人　地盤工学会"}]},"item_3_relation_191":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://doi.org/10.3208/jgs.4.205","subitem_relation_type_select":"DOI"}}]},"item_3_rights_192":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"c2009 公益社団法人　地盤工学会"}]},"item_3_select_195":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"佐藤, 厚子","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"42695","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"中村, 大","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"44835","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"90301978","nameIdentifierScheme":"KAKEN","nameIdentifierURI":"https://nrid.nii.ac.jp/ja/nrid/1000090301978 "}]},{"creatorNames":[{"creatorName":"鈴木, 輝之","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"42697","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"西本, 聡","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"42698","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-11-22"}],"displaytype":"detail","filename":"2009_自然寒冷下での凍結融解過程における高含水比土の水分挙動.pdf","filesize":[{"value":"1.5 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"2009_自然寒冷下での凍結融解過程における高含水比土の水分挙動.pdf","url":"https://kitami-it.repo.nii.ac.jp/record/8156/files/2009_自然寒冷下での凍結融解過程における高含水比土の水分挙動.pdf"},"version_id":"fbb41aab-df88-4ffd-b901-79d521fa439e"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"frost heave","subitem_subject_scheme":"Other"},{"subitem_subject":"freeze-dry","subitem_subject_scheme":"Other"},{"subitem_subject":"high water content","subitem_subject_scheme":"Other"},{"subitem_subject":"improving","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"自然寒冷下での凍結融解過程における高含水比土の水分挙動","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"自然寒冷下での凍結融解過程における高含水比土の水分挙動","subitem_title_language":"ja"},{"subitem_title":"Change of moisture content of unsuitable soil through freezing and thawing process appeared in natural cold climate","subitem_title_language":"en"}]},"item_type_id":"3","owner":"1","path":["86"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2016-04-04"},"publish_date":"2016-04-04","publish_status":"0","recid":"8156","relation_version_is_last":true,"title":["自然寒冷下での凍結融解過程における高含水比土の水分挙動"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-13T02:21:43.158648+00:00"}
