Quantitative Analyses on Damage to Buried Pipelines　due to 1983 Middle Japan Sea Earthquake 70026269 北浦, 勝 70143881 宮島, 昌克 70026269 Kitaura, Masaru 70143881 Miyajima, Masakatsu The 1983 Middle Japan Sea Earthquake (M=7.7) which occurred off the west coast AKita Prefecture caused extensive damage to lifeline systems. The authors already reported the results of field investigations. The present paper discusses the damage to the buried pipelines due to liquefaction. The purposes of the present study are to analyze the damage of pipelines quantitatively employing a statistical method and to make clear the failure mode of the buried pipeline. It became evident from the present study that the damage to pipeline was strongly influenced by the state of ground, especially soil liquefaction. 1985-10-09 金沢大学工学部 Faculty of Technology Kanazawa University 1985-10-09 2022-01-27 eng departmental bulletin paper VoR https://doi.org/10.24517/00065285 http://hdl.handle.net/2297/00065285 https://kanazawa-u.repo.nii.ac.jp/records/59023 10.24517/00065285 AN00044309 0022-832X 金沢大学工学部紀要 Memoirs of the Faculty of Technology Kanazawa University 18 2 57 65 https://kanazawa-u.repo.nii.ac.jp/record/59023/files/AN00044309-18-2-57-65.pdf application/pdf 324.4 kB 2022-01-27
