DESIGN METHOD OF CONCRETE STRUCTURE IN MAN-MADE ISLAND UNDER LARGE AND UNEVEN SETTLEMENT

Abstract

  Underpass structures for a public road and a airport service pass were constructed under the south taxiways in the second manmade island of Kansai International Airport. Two major issues in this construction were studied. One was prediction of large and uneven settlement of manmade-island under the structures, and the other was the design method of the structures in such a condition.
  In this paper, the design methods of underpass structures under uneven settlement of manmade-island were proposed after analyzing the site measurement and observation.
