The problem is solved by modeling the slip along the cracks as a continuous distribution of screw dislocations. The unknown dislocation density distribution is found by solving numerically the system of integral equations. The stress field induced by a single antiplane crack and two colinear cracks is studied and compared with that due to inplane shear cracks. The results are applied to some problems of geophysical interest. It has been found that both the free surface and lateral inhomogenities of the medium should have an effect on seismic and aseismic activity following major faulting in the medium. Also, the breaking of a barrier or seismic gap should result in a stress increase in the regions outside the fracture zone.","subitem_description_type":"Abstract"},{"subitem_description":"鉛直面により剛性率の異なる領域に2分された半無限媒質中に2つの横ずれ型shear crackがある場合につき,その相互作用を解析した・解析にあたり,クラックのすべりを模式化し,らせん型くいちがいが連続的に分布しているものとする.一連の積分方程式を数値的に解く事により,くいちがいの分布密度を求める事ができる.横ずれクラックが1個の場合,及び,2つのクラックが一線上に並んでいる場合の応力場を求め,クラックが縦ずれ型の場合と比較した.以上を用いて地球物理学的に重要な問題を考察したところ,地殻内に主断層が生じた後の地震活動(非地震的変形を含む)は,自由表面及び媒質の水平不均質性に影響されるものであることが判った.さらに,既存のバリアあるいは地震空白域が消失した場合には,破砕帯外側の領域に応力の増加をもたらす事が判った.","subitem_description_type":"Abstract"}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/0000032928","subitem_identifier_reg_type":"JaLC"}]},"item_4_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学地震研究所"}]},"item_4_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00162258","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00408972","subitem_source_identifier_type":"ISSN"}]},"item_4_subject_15":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"453","subitem_subject_scheme":"NDC"}]},"item_4_text_21":{"attribute_name":"出版者別名","attribute_value_mlt":[{"subitem_text_value":"Earthquake Research Institute, University of Tokyo"}]},"item_4_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"Institute of Geophysics, Polish Academy of Sciences"},{"subitem_text_value":"Earthquake Research Institute"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Niewiadomski, Janusz"}],"nameIdentifiers":[{"nameIdentifier":"128395","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Rybicki, Kacper"}],"nameIdentifiers":[{"nameIdentifier":"128396","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":"2017-06-26"}],"displaytype":"detail","filename":"ji0591003.pdf","filesize":[{"value":"1.0 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ji0591003.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/32928/files/ji0591003.pdf"},"version_id":"b71b45e8-b372-44e3-9154-117719de7585"}]},"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":"The Stress Field Induced by Antiplane Shear Cracks : Application to Earthquake Study","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"The Stress Field Induced by Antiplane Shear Cracks : Application to Earthquake Study","subitem_title_language":"en"}]},"item_type_id":"4","owner":"1","path":["4795","4796"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2008-05-30"},"publish_date":"2008-05-30","publish_status":"0","recid":"32928","relation_version_is_last":true,"title":["The Stress Field Induced by Antiplane Shear Cracks : Application to Earthquake Study"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-19T04:08:50.033119+00:00"}
