Abstract
In the course of a step-by-step reclaiming work on the soft ground having cohesive soil ranging from 10m thick to 20m thick, a thin-layer spreading operation was conducted as a method for the first-stage reclaiming, using a simplified floating conveyor system placed above the sea. This system had features such as drawing light and being capable of adjusting the body lcngth flexibly, which proved to be very effective in a reclaiming work of the region where the site is confined and shallow. Also, this method could prevent the sliding failure of spreading work, and made the favorable constructive precision possible.
