The utmost difficulties for its construction work were the laying down of 19 thousand tons of steel caisson as the wholeshape mold for the casting of underwater concrete. The strait's harsh physical conditions such as swift tidal currents of up to eight knots, as well as heavy sea traffic in which 1, 400 ships cruise every day, required swift laying-down operation of large scale construction facilities, with the setting accuracy within±10cms.<br>This paper introduces the problems concerning the laying-down of steel caisson, and the ways and means employed to overcome those difficulties."},{"@language":"ja","@value":"明石海峡大橋主塔基礎は海面下60mを支持面とする, 直径80m高さ70m体積35万m<sup>3</sup>の直接基礎であり, 施工上の最大の難関は水中コンクリートの全形型枠となる総重量1万9千tf (18万6千kN) のケーソンの設置であった. 明石海峡は最大潮流速が8knを超え, しかも1日あたり1400隻の船舶が航行する海上交通の要衝の地であり, ケーソンの設置にあたっては, 強大な外力に対抗するための設備の大型化とともに正確さと迅速性の確保が課題であったが, 設置誤差10cm以下で設置することができた. 本文では, ケーソンの設置にあたって, 何が問題であり, それをどのように解決したかについて述べる."}],"abstractLicenseFlag":"disallow"}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1410569723187567618","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000254310938"}],"foaf:name":[{"@language":"en","@value":"Kashima Satoshi"},{"@language":"ja","@value":"加島 聰"}],"jpcoar:affiliationName":[{"@language":"ja","@value":"社団法人土木学会"},{"@language":"ja","@value":"本州四国連絡橋公団第一建設局"}]},{"@id":"https://cir.nii.ac.jp/crid/1410569723187567616","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000254310939"}],"foaf:name":[{"@language":"en","@value":"Sakamoto Mitsushige"},{"@language":"ja","@value":"坂本 光重"}],"jpcoar:affiliationName":[{"@language":"ja","@value":"社団法人土木学会"},{"@language":"ja","@value":"本州四国連絡橋公団第一建設局機械課"}]},{"@id":"https://cir.nii.ac.jp/crid/1410569723187567617","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000254310940"}],"foaf:name":[{"@language":"en","@value":"Suzuki Motohiro"},{"@language":"ja","@value":"鈴木 幹啓"}],"jpcoar:affiliationName":[{"@language":"ja","@value":"社団法人土木学会"},{"@language":"ja","@value":"本州四国連絡橋公団第一建設局洲本工事事務所"}]},{"@id":"https://cir.nii.ac.jp/crid/1410569723187567619","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000254310941"}],"foaf:name":[{"@language":"en","@value":"Higuchi Kozo"},{"@language":"ja","@value":"樋口 康三"}],"jpcoar:affiliationName":[{"@language":"ja","@value":"社団法人土木学会"},{"@language":"ja","@value":"本州四国連絡橋公団第二管理局坂出管理事務所"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"02897806"},{"@type":"EISSN","@value":"18827187"}],"prism:publicationName":[{"@language":"en","@value":"Doboku Gakkai Ronbunshu"},{"@language":"ja","@value":"土木学会論文集"},{"@language":"en","@value":"Doboku Gakkai Ronbunshu"},{"@language":"ja","@value":"土木学会論文集"}],"dc:publisher":[{"@language":"en","@value":"Japan Society of Civil Engineers"},{"@language":"ja","@value":"公益社団法人 土木学会"}],"prism:publicationDate":"1997-12-20","prism:volume":"1997","prism:number":"581","prism:startingPage":"27","prism:endingPage":"37"},"reviewed":"false","url":[{"@id":"https://www.jstage.jst.go.jp/article/jscej1984/1997/581/1997_581_27/_pdf"}],"availableAt":"1997-12-20","foaf:topic":[{"@id":"https://cir.nii.ac.jp/all?q=caisson","dc:title":"caisson"},{"@id":"https://cir.nii.ac.jp/all?q=tide","dc:title":"tide"},{"@id":"https://cir.nii.ac.jp/all?q=quick%20joint","dc:title":"quick joint"},{"@id":"https://cir.nii.ac.jp/all?q=linear%20winch","dc:title":"linear winch"},{"@id":"https://cir.nii.ac.jp/all?q=information%20control","dc:title":"information control"}],"dataSourceIdentifier":[{"@type":"JALC","@value":"oai:japanlinkcenter.org:0005082370"},{"@type":"CROSSREF","@value":"10.2208/jscej.1997.581_27"},{"@type":"CIA","@value":"130003801136"}]}
