Abstract
Tokyo international Airport Offshore Development Project has been carried out on super soft ground composed of waste disposal field. There were many technical limitation under which ground improvement is performed. Airport foundation was formed by various kinds of invention in design and construction. This report outlines three features as follows: outstanding subjects on foundation engineering in airport construction on super soft ground, design and construction of ground improvement in the third stage zone under the most difficult environment in construction, the actual effect of ground improvement shown by proposed observation-construction management system.
