Abstract

In this study, field tests were conducted to analyze the pull-out behavior of plate anchor pins used in stone nets, which are commonly applied for river reinforcement. The maximum pull-out load and ground behavior were evaluated based on the length of the anchor pins and the size of the plate. A comparative analysis was also performed with existing theoretical formulas. The field test results showed that the maximum pull-out load was directly proportional to the length of the anchor pins and the surface area of the plates. Furthermore, the comparison with theoretical formulas indicated that the ultimate pull-out load observed in the field tests exhibited similar trends to the M&A and D&C theoretical models, depending on the installation depth and plate width. It is expected that continuous research and field tests under various ground conditions will contribute to improving the design and performance of river disaster prevention structures.

본 연구에서는 하천 보강으로 주로 사용되는 스톤네트의 플레이트 앵커핀 인발에 따른 거동을 분석하기 위해 앵커핀의 길이와 플레이트 판의 크기에 따른 인발하중과 지반 거동을 현장 시험을 통해 고찰하고, 기존 이론식과 비교·분석을 수행하였다. 현장시험 결과 최대 인발하중의 크기는 앵커핀의 길이 및 플레이트 판의 면적과 비례하는 것으로 나타났으며 이론식과의 비교 분석 결과 현장시험에 따른 극한인발하중은 설치심도 및 플레이트 폭의 변화에 따라 Meyhof and Adams 이론식과 Down and Chieurzzi 이론식과 비슷한 경향성을 나타냄을 확인하였다. 본 연구를 기반으로 지속적인 연구 및 다양한 지반조건에서의 현장 시험을 통해 하천방재시설물의 설계 기술 성능 향상에 기여할 수 있는 기초자료를 제공할 수 있을 것으로 판단된다.
