Assuming the descriptive cylindrical soil model representing sand, gravel/cobbles and void structures and applying the continuity law of water movement to the soil model, the functional relationship between the hydraulic conductivity of the sand sediment soil to be evaluated, the hydraulic conductivity of the sand soil measured by the laboratory or field permeability test, and the mass content of the gravel and cobbles in the soil was derived. The accuracy of the functional relationship mentioned above was examined by the series of the one-dimensional permeability test. A good comparison between the measurements and the estimation by the functional relationship was obtained. A numerical example was given to show the practical influence of the mass content of the gravel/cobbles on the prediction of the storm runoff in the sand sediment soil.", "subitem_description_type": "Abstract"}, {"subitem_description": "礫と巨石が混入する土砂堆積地盤の透水係数の推定方法を提案した。まず、土砂堆積地盤を構成する砂、礫・巨石および間隙を模式的に表した円筒状の土要素モデルを想定し、流れの連続条件を適用した。これにより、土砂堆積地盤全体の透水係数、室内あるいは現場透水試験で測定される砂の透水係数、ならびに土中に占める礫・巨石の質量含有率の関係を記述する理論式を誘導した。次に、この理論式の精度を、室内一次元透水試験により調べた。試験結果と理論式から推定した値の間に良好な一致が得られた。最後に、土砂堆積地盤における豪雨流出問題を対象に、流出量の推定結果に与える礫・巨石含有率の影響を示した。", "subitem_description_type": "Abstract"}]}, "item_7_full_name_3": {"attribute_name": "著者別名", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "163938", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "森井, 俊広"}]}]}, "item_7_publisher_7": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "新潟大学農学部"}]}, "item_7_select_19": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_7_source_id_11": {"attribute_name": "書誌レコードID", "attribute_value_mlt": [{"subitem_source_identifier": "AN00183393", "subitem_source_identifier_type": "NCID"}]}, "item_7_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "03858634", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Morii, Toshihiro"}], "nameIdentifiers": [{"nameIdentifier": "163937", "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": "2019-08-20"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "KK_55(2)_161-167.pdf", "filesize": [{"value": "438.6 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 438600.0, "url": {"label": "KK_55(2)_161-167.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/28499/files/KK_55(2)_161-167.pdf"}, "version_id": "35fa4507-e7c3-48b7-8754-3cc9ce40abf0"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "Sand sediment soil", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Hydraulic conductivity of soil", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Mass content of gravel and cobbles", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Laboratory permeability test", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Numerical calculation", "subitem_subject_scheme": "Other"}, {"subitem_subject": "土砂堆積地盤", "subitem_subject_scheme": "Other"}, {"subitem_subject": "土の透水係数", "subitem_subject_scheme": "Other"}, {"subitem_subject": "礫・巨石の質量含有率", "subitem_subject_scheme": "Other"}, {"subitem_subject": "室内透水試験", "subitem_subject_scheme": "Other"}, {"subitem_subject": "数値計算", "subitem_subject_scheme": "Other"}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "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": "Determination of Hydraulic Conductivity of Sand Sediment Soil Taking an Inclusion of Gravel and Cobbles into Account", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Determination of Hydraulic Conductivity of Sand Sediment Soil Taking an Inclusion of Gravel and Cobbles into Account"}, {"subitem_title": "Determination of Hydraulic Conductivity of Sand Sediment Soil Taking an Inclusion of Gravel and Cobbles into Account", "subitem_title_language": "en"}]}, "item_type_id": "7", "owner": "1", "path": ["456", "1611"], "permalink_uri": "http://hdl.handle.net/10191/17327", "pubdate": {"attribute_name": "公開日", "attribute_value": "2012-01-31"}, "publish_date": "2012-01-31", "publish_status": "0", "recid": "28499", "relation": {}, "relation_version_is_last": true, "title": ["Determination of Hydraulic Conductivity of Sand Sediment Soil Taking an Inclusion of Gravel and Cobbles into Account"], "weko_shared_id": null}
