초록

본 논문은 지반 적용을 위한 사면붕괴 억제 타이백 벽체설계의 주제에 관한 여러 가지 설계고려사항을 검토해보았다. 설계는 특정 지역 조건에 맞는 벽체를 설계하기 위한 토질역학과 지질학의 복합된 지식을 요구한다. 설계를 완성하기 위한 많은 측면들이 여전히 완벽하게 연구되어 있지 않다. 본 논문은 기존의 타이백 벽체설계에 관한 개요와 suppressor 벽체 지중압력/타이백에 기인한 응력 회전과 같은 새로운 이슈의 토론 등을 기술하였다. 지진력의 효과에 관해서도 서술하였다.

This paper reviews many of the design considerations surrounding the topic of tiedback landslide suppressor walls primarily for soils app1ications. The design requires combining knowledge of many aspects of soil mechanics and geology to obtain a design a wall that fits site specific conditions. Many of the aspects necessary to complete the design are stil1 not comprehensively studied or understood. This paper provides an overview of the more traditional aspects of tieback wall design and a discussion of newer issues such as suppressor wall earth pressures and rotation of stresses due to tiebacks. An overview is also provided regarding the effect of seismic forces.
