dc.description.abstract본 연구에서는 상.하단으로 구분된 2개의 동일한 보강토옹벽에 대해서 상호 이격거리에 따른 수치해석을 수행하여 전면벽체의 수평변위, 전면벽체 배면의 수평토압, 보강토체 배면의 수평토압 그리고 보강재의 최대인장력 분포 및 크기변화 양상 등 다단식 보강토옹벽의 거동을 살펴보았다. 또한, 하단 옹벽에 증가되는 응력을 산정하고자 중첩의 원리를 적용한 2:1 응력분포법을 제시하였다. 수치해석 결과 이격거리가 증가함에 따라 상단옹벽이 하단옹벽에 미치는 영향이 감소하였으며 하단 옹벽 높이의 두배 이상 이격시, 상호 거동은 독립옹벽으로 거동하였다. 하단 옹벽내 응력 산정방법에 있어서 NCMA의 방법이 가장 보수적인 결과를 보였으며 본 연구에서 제시한 2:1 응력분포법중 주동파괴면을 고려하지 않은 방법이 수치해석 결과와 가장 유사하게 나타났다. In this study, in order to assess the behavior of multi-reinforced earth retaining walls, two reinforced earth retaining walls which have the identical geometry and configuration are presented and analyzed in the cases of several set back distances. The horizontal displacement of facing, lateral earth pressure behind both facing and reinforced earth body, and maximum tensile force in reinforcement are obtained from the numerical analysis. Also, 2:1 stress distribution method based on superposition principle is proposed to estimate the increasing stress distribution of the lower wall due to the upper wall. The results of analysis show that the influence upper wall on the lower one decrease according to the increase of set back distance, and when the set back distance is two times as great as the height of the lower one, the behaviour of each wall works independently. When the increasing stress of the lower wall due to the upper one was calculated, NCMA(National Concrete Masonry Association) method using uniform surcharge was the most conservative, and the stress increase obtained from 2:1 method without consideration of active failure surface was similar to the result of numerical analysis.en_US
