Abstract
The tuff gravel transported from the midland of Kobe city was used for the reclemation work at Kobe Airport, which was constructed offshore about 8km distant from the Kobe city center. In this project, the compressive defomation of the submerged embankment during the reclematon work was measured by means of a newly developed instrumentation equipped with a pressure guage. The system is capable of measuring automatically the vertical deformation of the reclaimed land by using the radio system. The rate of volume change during the reclamation work below and above the sea-water level was manifested. The applicability of this monitoring system was successfully demonstrated for the case of rapid reclemation work in deep sea and on poor sea-bed conditions.
