Abstract
The life cycle analysis method is proposed for geogrid reinforced soil wall. The proposed method evaluates life cycle cost as total cost of initial cost, maintenance cost and seismic risk. This paper shows the standard evaluation method of the seismic risk which is a product of failure probability and seismic disaster costs. Based on the proposed method, LCC of geogrid reinforced soil wall, L-shaped RC wall and no-reinforced embankment were compared. It is cleared that LCC of the geogrid wall is the lowest in spite of traffic volume and structure length. Content of this paper is from achievement produced by Technical Committee: Stage 5 established in IGS Japan chapter (2010-2012).
