This paper aims to study the influence of geosynthetics along with gravel usage to reduce the vertical soil displacement caused by liquefaction using a shake table equipment. This influence is analyzed by means of measuring soil acceleration, pore water pressures and vertical soil deformation due to the shaking process.\n\nResults\nResults of a series of 1-g shaking table tests which have been conducted in different initial relative densities which are 50% (loose sand conditions) and 90% (dense sand conditions) to evaluate the performance of proposed mitigation against settlement problem are presented. It is found that ground settlement reduced around 11.4 mm for loose sand conditions, from 20.9 mm in the case with no countermeasure (Case 1) to 9.5 mm in the Case reinforced with gravel and geosynthetics Type II (Case 4). Correspondingly, for dense sand states, the settlement decreased by about 1.8 mm, from 5.6 mm in the Case 1 to 3.8 mm in Case 4. Moreover, a differential settlement between loose sand and dense sand conditions decreased as well, around 9.6 mm, from 15.3 mm in the Case 1 to 5.7 mm in Case 4.\n\nConclusions\nBy conducted a series of shake table tests, it is confirmed that the vertical ground displacement decreased by the use of geosynthetics and gravel up to 54% and 32% for loose sand and dense sand states, respectively. Furthermore, test results also show that there is a decrease in the differential settlement between loose sand and dense sand conditions, around 62%.","subitem_description_type":"Abstract"}]},"item_4_description_5":{"attribute_name":"提供者所属","attribute_value_mlt":[{"subitem_description":"金沢大学理工研究域地球社会基盤学系","subitem_description_type":"Other"}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24517/00064894","subitem_identifier_reg_type":"JaLC"}]},"item_4_publisher_17":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"International Consortium on Geo-disaster Reduction (ICGdR) / Springer"}]},"item_4_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1186/s40677-018-0115-3","subitem_relation_type_select":"DOI"}}]},"item_4_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://geoenvironmental-disasters.springeropen.com/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://geoenvironmental-disasters.springeropen.com/","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://geoenvironmental-disasters.springeropen.com/articles/10.1186/s40677-018-0115-3"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://geoenvironmental-disasters.springeropen.com/articles/10.1186/s40677-018-0115-3","subitem_relation_type_select":"URI"}}]},"item_4_rights_23":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Copyright © The Author(s). 2018 Open Access This article is distributed under the terms of the Creative Commons Attribution 4.0 International License (http://creativecommons.org/licenses/by/4.0/), which permits unrestricted use, distribution, and reproduction in any medium, provided you give appropriate credit to the original author(s) and the source, provide a link to the Creative Commons license, and indicate if changes were made."}]},"item_4_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2197-8670","subitem_source_identifier_type":"ISSN"}]},"item_4_version_type_25":{"attribute_name":"著者版フラグ","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":"Setiawan, Hendra"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Serikawa, Yuko"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Sugita, Wataru"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kawasaki, Hajime"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Miyajima, Masakatsu"}],"nameIdentifiers":[{},{},{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2022-01-28"}],"displaytype":"detail","filename":"TE-PR-MIYAJIMA-M-2018-5.22.pdf","filesize":[{"value":"2.4 MB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"TE-PR-MIYAJIMA-M-2018-5.22.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/58626/files/TE-PR-MIYAJIMA-M-2018-5.22.pdf"},"version_id":"6202a9fc-7ae2-4e62-bbd5-82e4b0093714"}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Experimental study on mitigation of liquefaction-induced vertical ground displacement by using gravel and geosynthetics","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Experimental study on mitigation of liquefaction-induced vertical ground displacement by using gravel and geosynthetics"}]},"item_type_id":"4","owner":"18","path":["936"],"pubdate":{"attribute_name":"公開日","attribute_value":"2022-01-28"},"publish_date":"2022-01-28","publish_status":"0","recid":"58626","relation_version_is_last":true,"title":["Experimental study on mitigation of liquefaction-induced vertical ground displacement by using gravel and geosynthetics"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2023-07-27T13:54:40.052372+00:00"}
