Abstract

Behaviour of soil nailed walls in Korea has been analysed based on a number of field measurements. The investigation has included interface shear strength development at the nail-soil interface from pull-out tests, lateral ground displacements, tensile force distributions along soil nails and mobilised interface shear stress distributions. Insights into the soil nailed wall behaviour based on the shear transfer mechanism at the soil-nail interface and partial mobilisations of the interface shear strength, governed by relative shear displacement, are reported and discussed. It is expected that results from the current research can provide relevant parameters required for preliminary design of soil nailed walls in Korea.

본 논문에서는 현장계측을 통해 관측된 소일네일링 벽체의 거동을 분석하였다. 연구의 주요내용으로는 인발시험을 통해 산정한 네일과 지반의 경계면에서 전단강도의 발생, 지반의 수평변위, 네일에 발생하는 인장력의 분포 및 경계면에서의 전단강도의 발현 등이다. 특히, 경계면에서의 전단응력 발생 과정 및 전단강도 발현에 대한 심도있는 분석을 실시하였다. 본 연구에서 분석된 자료는 국내 소일네일링의 예비설계 단계시 참고 자료로 활용될 수 있을 것으로 기대된다.
