본 논문에서는 도로확장공사 현장의 절토사면 안정검토를 위해서 몇가지 조사 및 분석을 수행하였다. 압성토 및 억지말뚝으로 보강된 절토사면의 추가 보강사례를 그 연구대상으로 하며, 절토사면에 보강된 안정화파일의 효과를 분석하기 위한 시험장비 또한 설계 및 설치하였다. 결론적으로, 추가보강방법으로써 억지말뚝공법과 Earth Anchor공법을 검토한 결과, 억지말뚝공법과 Earth Anchor공법 모두 안정성은 확보하였으나 기존 보강공법의 연계성과 경제성을 고려하여 억지말뚝공법을 추가보강공법으로 선정하였다. To confirm the stability of a cut slope in the road extension construction site, several investigations were carried out and countermeasures of slope was studied. This paper describes a study of design case of extra reinforcement on existing cut slope reinforced by preloading and piles in roads. To investigate the effect of stabilizing piles installed in a cut slope, an instrumentation system also designed, was. As a result that the stabilizing file and earth anchor are considered as the extra reinforcement, both stabilizing pile and earth anchor guarantee the stability of cut slope. However, stabilizing pile is selected in aspects of economy and continuity to the existing cut slop reinforcement including counterweight fill and stabilizing piles.

Most structures were designed by allowable stress method instead of performance-based design such as pile, foundations etc. Nowadaya, several countries have studied on this subjects. In is paper, design schemes of performance-based methods are studied for designsystem, maintenance stages, which more considerations should be continued in geotechnical field.
