東京スカイツリー^®の建設

～世界一の高さへの挑戦～

抄録

This paper presents the construction project of TOKYO SKYTREE, which has been completed in February 2012 as the world's tallest broadcasting tower with the height of 634 m. There were many technologies and engineering adopted to this unprecedented project, including but not limited to: the extraordinary wall foundation that support the tower with a very small footprint, the unique vibration control system that depress the seismic shake of the tower by a half, “lift-up construction method” of the antenna spire that eliminated variety of problems associated with working at an extreme altitude, and the very rapid construction of the reinforced concrete core column using “slip form construction method”. All of those were indispensable for the successful completion of the project, ensuring the safety and the quality while shortening the construction period.
