We set 8 measure points and measured the frost-heaving height of each point at intervals of about 10 days from early in December to early in April. As a result, it appears follows. 1. there is nearly connection between frost-heaving and solar rediation. Frost-heaving is higher at hide place than at sunny place and also the period of frost-heaving is longer at hide place than at sunny place. 2. In each position of road, the frost-heaving is lowest at shoulder and lower at the cutting side then at banking side. 3. It is no effection of ballast less than 10cm depth to decrease og frost-heaving. 4. There is an inverse relation between frost-heaving and temperature. At hide place the frost-heaving reachs highest level at late in February and finishs at late in March, but at sunny place 15～20 days earlier than hide place. 5. Ae rain in March accelerates the thaw.","subitem_description_type":"Abstract"}]},"item_10_description_30":{"attribute_name":"資源タイプ（コンテンツの種類）","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_10_description_5":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"信州大学農学部演習林報告 28: 37-50(1991)","subitem_description_type":"Other"}]},"item_10_publisher_4":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"信州大学農学部附属演習林"}]},"item_10_source_id_35":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0559-8613","subitem_source_identifier_type":"ISSN"}]},"item_10_source_id_40":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00121330","subitem_source_identifier_type":"NCID"}]},"item_1627890569677":{"attribute_name":"出版タイプ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"井,  博道"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"井上,  裕"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2015-09-25"}],"displaytype":"detail","filename":"Agri_Forests-28-03.pdf","filesize":[{"value":"623.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"Agri_Forests-28-03.pdf","url":"https://soar-ir.repo.nii.ac.jp/record/11219/files/Agri_Forests-28-03.pdf"},"version_id":"0202b7ab-1e25-4bbc-980a-3806415e684a"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"冬期における林道の路面凍上について","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"冬期における林道の路面凍上について","subitem_title_language":"ja"},{"subitem_title":"Research in the Frost-heaving of Forest Road in Winter","subitem_title_language":"en"}]},"item_type_id":"10","owner":"1","path":["1114"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2012-03-07"},"publish_date":"2012-03-07","publish_status":"0","recid":"11219","relation_version_is_last":true,"title":["冬期における林道の路面凍上について"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-14T03:59:11.986610+00:00"}
