Abstract
Because it has been proven that soil obtains a big strength and bearing capacity by completely rolling it like “soil bag”, a new reinforcement method of wrapping soil with geotextile is presented. The method of calculating the tension in the geotextile is shown. Moreover, the loading tests on the reinforced test embankment are performed. The test embankment is 1.8m in height, and 1.5m in upper width. The load on the test embankment is increased as much as 300kN/m2, and the geotextile strain, the deformation of the wall face and the earth pressure are measured. As a result, it is confirmed that the method of calculating the tension is valid and the deformation of the wall face becomes small by rolling soil.
