The first purpose of this paper is to examine the pore water pressure fluctuation in shallow and deep stratum at the slip surface. The data used in this study was collected at the Tairasawa landslide area during 1983-1985. Two observational methods are considered. (1) The pressure heads were measured in the vertical observation borehole with a screened section at the designated depth of slip surface. (2) The horizontal borehole of drainage wells were drilled for confined groundwater in a screened section at the same depth of the slip surface. The rainfall, pressure head and drainage discharge were observed before and after the drainage well works.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"54260","nameIdentifierScheme":"WEKO"}],"names":[{"name":"TSAO, Tsungming"}]}]},"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農学国際専攻"},{"subitem_text_value":"Department of Global Agricultural Sciences, Graduate School of Agricultural and Life Sciences, The University of Tokyo"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"曹, 崇銘"}],"nameIdentifiers":[{"nameIdentifier":"54259","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":"esrh104001.pdf","filesize":[{"value":"5.0 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"esrh104001.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/25358/files/esrh104001.pdf"},"version_id":"143ef654-8147-4d44-92ed-7a2ebdd952a2"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"地すべり","subitem_subject_scheme":"Other"},{"subitem_subject":"間隙水圧","subitem_subject_scheme":"Other"},{"subitem_subject":"集水ボーリング","subitem_subject_scheme":"Other"},{"subitem_subject":"すべり面","subitem_subject_scheme":"Other"},{"subitem_subject":"集水井","subitem_subject_scheme":"Other"},{"subitem_subject":"Landslide","subitem_subject_scheme":"Other"},{"subitem_subject":"Pore water pressure","subitem_subject_scheme":"Other"},{"subitem_subject":"Horizontal borehole","subitem_subject_scheme":"Other"},{"subitem_subject":"Slip surface","subitem_subject_scheme":"Other"},{"subitem_subject":"Drainage well","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":"地すべり地地下水の挙動に関する実験的研究地下水排除工と地すべり移動との関係","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"地すべり地地下水の挙動に関する実験的研究地下水排除工と地すべり移動との関係"}]},"item_type_id":"4","owner":"1","path":["2534","2533"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-07-17"},"publish_date":"2012-07-17","publish_status":"0","recid":"25358","relation_version_is_last":true,"title":["地すべり地地下水の挙動に関する実験的研究地下水排除工と地すべり移動との関係"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T03:59:35.100198+00:00"}
