다국어 초록 (Multilingual Abstract)

Most of the problems related to drainage during the construction of the reinforced earth retaining wall structure do not occur during construction on the flat ground. However, when the reinforced earth retaining wall is installed in a place where the cut slope or the high embankment, problems related to drainage often occur. Problems associated with drainage on the reinforced earth retaining wall start with the leakage of the front wall part initially. When the front wall is wet by water, leaving it lightly is likely to develop into a big problem later on. If some of the construction is wetted by water, tracing back the flow of water or smoothly draining the already saturated backfill water has a positive effect on the stability of the structure. In some sites, the reinforced earth retaining wall is located at the end of the high embankment, and the surface is drained only in a part of the section, so that no consideration is given to the phenomenon that the upper surface number saturates the filler behind the reinforcing earth retaining wall. When slopes ranging from tens of meters to the top of reinforcing earth retaining wall and the end of embankment are formed, a plan should be prepared to actively drain the surface water.
Therefore in this study, an analysis of the case study on the site was presented to solve the problem of drainage of reinforced earth retaining wall.
