This paper presents a new earth reinforcement by soilbags and its applications in Japan to such earth reinforcement as reinforcement for ballast foundations under railway sleeper, reinforcement for soft building foundations and construction of retaining walls.

A number of soilbags are usually piled up to construct a face wall in the embankment reinforced with horizontal geotex-tiles.

Pinghu Beach Reclamation Project from Baishawan to Shuikou is the first one carried out by the combination of piping package earthwork and pavement structure,the main part of which has been finished after 2 years construction.

The mechanism and properties of soilbags are introduced.

A method of reinforcing expansive soil with soilbags had been proposed and verified the availability by laboratory and field tests.

The procedure of construction with earth-bag cofferdam is introduced for the open-cut foundation in deep water and sandy soil with a narrow space at Pier No.

The authors demonstrate on the feasibility of the scheme from the aspects including bagged soil, selection construction requirement, consolidation speed of dam foundation, as well as the overall stability of the reclamation dam.
