Damage Characteristics on Reinforced Earth Retaining Walls Constructed Multi - Stage in Expressway
Reinforced earth retaining walls are applied to various fields such as clay part, cut part, adjacent part of structure (alternation, culvert) and reinforcement soil alternation in Korea. Therefore, they are applied more favorably than concrete retaining wall because of its excellent economy and construction. Analysis of reinforced earth retaining wall construction shows that the height is more than 10m higher than that of foreign countries, and when it is applied in multi - stage, it is more than 20m. The reinforced earth retaining wall was introduced in Korea in the 1980s, and the number of years of damage has been increasing due to the fact that the number of public years has been increased to 30 years since it was first applied to the present. Especially, in the case of multi-stage reinforced earth retaining walls having a height of 10 m or more, And the risk of the risk to reach the situation is found. Therefore, in this study, damage characteristics occurred in reinforced earth retaining wall constructed in multi - stage in expressway were analyzed.
