| Abstract | This paper introduces the structural design and construction method for the foundation of the TOKYO SKYTREE, a new digital broadcasting tower in Tokyo, which has a height of 634 meters. The surface layer of the ground is occupied by soft soil, thus the foundation of this tower is an SRC continuous underground wall pile, designed and developed to have horizontal rigidity and pull-out resistance. The structural integrity and construction method of the wall pile was verified with a full scale pull-out test, determining a maximum load of 40,000 kN for a full scale wall pile. |
