초록

본 연구에서는 개량토 벽면공을 활용한 보강성토사면의 거동에 대하여 실내모형시험 및 수치해석을 통해 분석하였다. 또한 수해발생현장에 이 연구에서의 방법을 이용하여 시험시공으로 보강성토사면을 구축한 후 약 6개월간 전면변위를 측정하여 실제 거동을 분석하였다. 실내모형시험, 수치해석, 현장시험 등을 통해 개량토 벽면공의 강성은 보강성토사면에서 충분한 벽면공의 역할을 수행할 수 있는 것으로 나타났고, 시험시공 후의 전면변위 측정결과 사면높이에 대한 수평변위의 비율은 최대 약 0.4%로 매우 안정적인 것으로 조사되었다.

This paper presents the slope wall technique using soil improvement material for reinforced soil slope through laboratory scale model tests, and verifies the experimental results comparing with numerical analysis. In additional, case study in field has performed to investigate the deformation of reinforced soil slope for 6 months. As a result of laboratory scale model test, numerical analysis, and case study, the reinforcement effect of the slope wall technique using soil improvement material is sufficient to be constructed as reinforced soil slope. The technique shows the stable ratio (0.4%) of horizontal to vertical deformation in the surface loading.
