DESIGN AND CONSTRUCTION OF BROAD UPPER PC-SLAB FOR OPEN CULVERT AGAINST AIRPLANE LOAD

Abstract

  Underpass structures for a public road and airport service pass were constructed under the south taxiways in the second manmade island of Kansai International Airport. Two major problems in this project were brought up. One was the prediction of uneven settlement of manmade-island, and the other was the design method of broad upper PC-slab in such a condition.
  In this paper, the design and construction methods of broad upper PC-slab for open culvert against airplane load are proposed, and their applications are confirmed by the loading test using heavy dump tracks and the measurement of slab deflection against a real maximum airplane load.
