Abstract

The soil nailing method has been developed on the basis of experimental works as well as theoretical backgrounds. As for the experimental research works, most of the data have been measured during the application of load in service. However, not only the soil-nailed structure behavior in service but also the failure behavior of the structure is major concern to evaluate and even establish a design method of soil-nailed walls. In this study, a relatively large-scale experiment was carried out to figure out the failure behavior of soil-nailed wall. A number of data such as displacement of soil-nailed walls, soil pressure in soil-nailed walls, atrial strain and axial force of nail etc.'have been acquired and analysis.

지반네일 보강방법은 이론적 뒷받침과 함께 경험적인 작업을 기초로 발전되어 왔다. 경험적인 연구 작업에서 대부분의 자료가 실질적으로 사용되는 하중 조건에서 계측 되어 왔다. 그러나, 지반네일 보강토체에 대한 사용 하중 내에서의 거동 뿐 아니라 구조물의 파괴 거동도 설계방법의 확립과 계산에 중요한 대상이 된다. 본 연구에서는 소일네일 보강토체의 파괴 거동을 이해하기 위하여 비교적 즐 규모의 실험을 실시하여 토체의 변위, 네일의 축변형률,네일의 축하중, 토체내 부의 토압 등에 관한 자료를 얻었으며 이러한 자료들을 분석하였다.
