초록

본 연구에서는 Wright 등이 제안한 산사태 억지벽체공법에, nailing system을 추가한 새로운 형태의 사면보강공법을 제시하였다. 이를 위해, nail로 보강된 콘크리트판넬에 작용하는 토압산 정법의 제시 및 억지말뚝 해석법의 정림 등이 이루어 졌다. 또한 제시된 토압산정법을 토대로, nail의 효율적인 배치형태 및 설치각도 등에 대한 분석과, 콘크리트판넬 및 억지말뚝으로 구성된 억지벽체의 최적설치위치에 관한 분석이 수행되었다. 이외에도 설계예를 통해, Wright 등의 제안방법과의 비교, 억지말뚝 상호간섭작용의 영향검토 등이 수행되었다.

This paper proposes a stabilizing method against landslide using slide suppressor wall reinforced with soil nails. Included are a procedure to predict earth pressures acting on the concrete panel and a method of analysis of stabilizing pile. Based on the proposed procedure, the efficient installation type and inclusion angle of nails are analyzed. Also, optimum location of the slide suppressor wall composed of concrete panel and stabilizing pile is analyzed. Finally the comparison with a method proposed by Wright is made, and the effect of interactions between stabilizing piles is examined, throughout the design example.
