Abstract

This study analyzes the lateral earth pressure of anchor-supported retaining walls using field monitoring data from excavation sites in Jeju Island and proposes a rational and economical design approach. Horizontal displacement tends to decrease with increasing wall stiffness, improved ground conditions, and lower excavation depth. Although numerical analysis reproduces the overall deformation trends, discrepancies are observed in both the magnitude and location of maximum displacement. These differences are considered to result from limitations of the constitutive model and uncertainties in geotechnical parameters. Therefore, accurate prediction of retaining wall behavior requires appropriate selection of analytical models and the use of reliable geotechnical parameters.

본 연구는 제주도 굴착 현장의 계측 데이터를 활용하여 앵커식 흙막이벽의 측방토압을 분석하고, 합리적이고 경제적인 설계 방안을 제시하고자 하였다. 수평변위는 벽체 강성이 클수록, 지반조건이 양호할수록, 터파기고가 낮을수록 감소하는 경향을 보였다. 수치해석은 전반적인 변형 경향을 재현하였으나, 최대변위의 크기와 발생 위치에서 차이가 나타났으며, 이는 구성모델의 한계와 지반정수의 불확실성에 기인하는 것으로 판단된다. 따라서 흙막이 벽체 거동의 정확한 예측을 위해서는 적절한 해석모델의 선정과 신뢰성 높은 지반정수의 적용이 필요하다.
