The predominant period of microtremors is determined from the spectra, which is used to illustrate the dynamic behavior of underground structure. As given in Table 1, the predominant period of about 0.3 to 0.5 sec. estimated in the shorter period range agrees to that generally observed in the mountains overlaying soft soil. Moreover, another predominant period is found to be about 1.0 to 1.2 sec. in the longer period range of the same spectra. From the correlation of the two predominant periods at each station shown in Fig. 4, it may be considered that the periods of about 0.3～0.5 sec. and about 1.0～1.2 sec. are corresponding to the first and the second mode oscillations in the underground structure respectively. The relative variation of spectral amplitude with the location of observation is discussed mainly for the two predominant periods, and is explained to be caused by the effect of viscosity in the superficial layer on the lower medium. It seems that the coefficient of viscosity varies from about 5 × 10v  to 5 × 10v  CGS on the boundary of the landslide area, the value in the moutain range being smaller than in the plain.","subitem_description_type":"Other"}]},"item_20004_description_20":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_20004_description_21":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_20004_description_22":{"attribute_name":"その他の資源識別子","attribute_value_mlt":[{"subitem_description":"信州大学工学部紀要 31: 87-104 (1971)","subitem_description_type":"Other"}]},"item_20004_full_name_16":{"attribute_name":"公開者(その他言語)","attribute_value_mlt":[{"nameIdentifiers":[{}],"names":[{"name":"信州大学工学部"}]}]},"item_20004_identifier_23":{"attribute_name":"資源識別子URI","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/10091/10987"}]},"item_20004_source_id_25":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0037-3818","subitem_source_identifier_type":"ISSN"}]},"item_20004_source_id_26":{"attribute_name":"処理レコードID(総合目録DB)","attribute_value_mlt":[{"subitem_source_identifier":"AN00121228","subitem_source_identifier_type":"NCID"}]},"item_20004_version_type_51":{"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_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"url":{"url":"https://soar-ir.repo.nii.ac.jp/?action=repository_action_common_download&item_id=13000&item_no=1&attribute_id=65&file_no=1"}}]},"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":"地すべり地における常時微動特性 : 新潟県高場山トンネル崩壊地","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"地すべり地における常時微動特性 : 新潟県高場山トンネル崩壊地"}]},"item_type_id":"20004","owner":"3","path":["2668"],"pubdate":{"attribute_name":"公開日","attribute_value":"2020-09-03"},"publish_date":"2020-09-03","publish_status":"0","recid":"35354","relation_version_is_last":true,"title":["地すべり地における常時微動特性 : 新潟県高場山トンネル崩壊地"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-05-15T20:06:40.209378+00:00"}
