Abstract

This paper deals with visual confirmation device for tensile force verification in order to cope with tensile force loss of ground anchor. Ground anchors are constructed to ensure the stability of social infrastructure facilities, but continuous loss of tensile force is seriously concerned about safety of the facilities. This requires the maintenance of the anchors, but the current measuring of residual tensile force is done by sampling, taking into account economic aspects, which limits precision. In this paper, conducted a conceptual design, tensile experiment, and field test for the purpose of developing an anchor tensile force visual device to check the tensile force of the anchors.

본 논문에서는 그라운드 앵커의 긴장력 손실에 대응하고자 긴장력 상시확인을 위한 앵커 긴장력 상시 육안확인장치에 대한 내용을 다루었다. 그라운드 앵커는 사회적 인프라 시설의 안정성을 확보하기 위해 시공되었지만 지속적인 긴장력 손실로 인해 시설물에 대한 안전이 심각하게 우려되고 있는 실정이다. 이에 앵커의 유지관리가 요구되지만 현재 잔존긴장력의 계측은 경제적인 측면을 고려하여 표본조사로 이루어지고 있어 정밀도에 대한 한계점을 지니고 있다. 따라서 본 논문에서는 앵커의 긴장력을 육안으로 확인할 수 있는 앵커 긴장력 상시 육안확인장치의 개발을 목적으로 개념설계, 실내 인장실험을 통한 규격화를 수행하였으며, 현장시험을 통해 성능을 확인하였다.
