GEOGRID REINFORCED SOIL WALL USING FOREST THINNING TO FACING PANEL

Abstract

In the Third Conference of the Parties to the UN Framework Convention on Climate Change, it was decided that some developed countries must reduce the defined amount of greenhouse gases from 2008 to 2012. Japan must cut down its annual emission of greenhouse gases by 6 % by 2012 from 1990 levels. The Japanese national and local governments planed to reduce the greenhouse gases by absorbing the gases in the forest, so that they promoted the thinning operation to grow the healthy forests. To utilize the thinned wood effectively, authors applied the forest thinning to the facing panel of reinforced soil wall. This paper reports the results of field investigation of the reinforced soil wall constructed in the past and refers to stability of the wall, corrosion condition of the thinned wood and vegetation condition.
