We constructed “No.1 route” of traditional typed spur road in advance and “No.2 route” of Ohasi-typed forest road then. We compared the quality of them. We used two methods for measuring bearing capacity: handy typed bearing capacity apparatus (CASPOL) and Yamanaka typed soil penetrometer and Sweden typed sounding tester as a sounding test.It results that “Ohasi-typed forest road” was higher bearing capacity of road surface than “No.1 route” of traditional typed spur road. A significant difference of average bearing capacity on the surfaces of them was found. The bearing capacity of the former was higher than the data of measuring before. Both CASPOL and Yamanaka typed soil penetrometer indicated same trends.By sounding test “Ohasi-typed forest road” has stronger road structure than that of normal typed spur road. “Ohasi-typed forest road” is effective in constructing the low cost forest road network system in spite of its high cost","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"53937","nameIdentifierScheme":"WEKO"}],"names":[{"name":"KOBAYASHI, Hiroshi"}]},{"nameIdentifiers":[{"nameIdentifier":"53938","nameIdentifierScheme":"WEKO"}],"names":[{"name":"NITAMI, Toshio"}]},{"nameIdentifiers":[{"nameIdentifier":"53939","nameIdentifierScheme":"WEKO"}],"names":[{"name":"ARUGA, Kazuhito"}]},{"nameIdentifiers":[{"nameIdentifier":"53940","nameIdentifierScheme":"WEKO"}],"names":[{"name":"SAKURAI, Rin"}]},{"nameIdentifiers":[{"nameIdentifier":"53941","nameIdentifierScheme":"WEKO"}],"names":[{"name":"SUGIURA, Naoshige"}]}]},"item_4_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学大学院農学生命科学研究科附属演習林"}]},"item_4_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00162451","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03716007","subitem_source_identifier_type":"ISSN"}]},"item_4_subject_15":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"610","subitem_subject_scheme":"NDC"}]},"item_4_text_21":{"attribute_name":"出版者別名","attribute_value_mlt":[{"subitem_text_value":"The Tokyo University Forests"}]},"item_4_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京大学大学院農学生命科学研究科森林科学専攻"},{"subitem_text_value":"宇都宮大学農学部森林科学科"},{"subitem_text_value":"Department of Forest Science, Graduate School of Agricultural and Life Sciences, The University of Tokyo"},{"subitem_text_value":"Department of Forest Science, Faculty of Agriculture, Utsunomiya University"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"小林, 洋司"}],"nameIdentifiers":[{"nameIdentifier":"53932","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"仁多見, 俊夫"}],"nameIdentifiers":[{"nameIdentifier":"53933","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"有賀, 一宏"}],"nameIdentifiers":[{"nameIdentifier":"53934","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"桜井, 倫"}],"nameIdentifiers":[{"nameIdentifier":"53935","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"杉浦, 直重"}],"nameIdentifiers":[{"nameIdentifier":"53936","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":"2017-06-09"}],"displaytype":"detail","filename":"esrh113007.pdf","filesize":[{"value":"6.5 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"esrh113007.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/25308/files/esrh113007.pdf"},"version_id":"6f209928-db4b-488c-9d66-b9ca90fd11d0"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"作業道","subitem_subject_scheme":"Other"},{"subitem_subject":"大橋式路網作設法","subitem_subject_scheme":"Other"},{"subitem_subject":"簡易支持力測定器","subitem_subject_scheme":"Other"},{"subitem_subject":"土壌硬度計","subitem_subject_scheme":"Other"},{"subitem_subject":"スエーデン式サウンデン","subitem_subject_scheme":"Other"},{"subitem_subject":"spur road","subitem_subject_scheme":"Other"},{"subitem_subject":"Ohasi-typed forest road","subitem_subject_scheme":"Other"},{"subitem_subject":"handy typed bearing capacity apparatus","subitem_subject_scheme":"Other"},{"subitem_subject":"Yamanaka typed soil penetrometer","subitem_subject_scheme":"Other"},{"subitem_subject":"Sweden typed sounding tester","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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"作業道の路体構造と支持力について","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"作業道の路体構造と支持力について"}]},"item_type_id":"4","owner":"1","path":["2516","2515"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-07-17"},"publish_date":"2012-07-17","publish_status":"0","recid":"25308","relation_version_is_last":true,"title":["作業道の路体構造と支持力について"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T04:03:37.958663+00:00"}
