Abstract
Reinforce a soil wall with geogrids has a soft structure characteristic. Therefore, bearing capacity is not really needed when you compare it to a concrete wall, such as a gravity retaining wall and a concrete L-shape retaining wall. However, constructing embankments on unstable soft ground is increasing for effective land use in recent years.
Moreover, there are also many cases that the embankment materials cannot keep friction such as cohesive soil and loam. Then, the writers thought it could be expected to get bearing capacity, and increase the friction with mixing foamed scrap glass, which is a lightweight granular object, into foundation soil material.
In this research, it has inspected the influence of the frictional resistance between geogrids and soil constant by changing the rate of mixture of the scrap glass.
In the experiment, it has examined that the more you increase the rate of mixture of the scrap glass, the more it increases the angle of shear resistance. Furthermore, it turned out that the friction characteristic between geogrids is the same as the mixed soil.
