Abstract

This study verified the stability of a high-strength combined buried pile retaining wall and its applicability in the field. A cast-in-place (C.I.P) retaining wall and the high-strength combined embedded pile retaining wall were compared and analyzed numerically. The numerical analysis assessed the ground behavior and stability (and thus field applicability) of a high-strength combined buried pile retaining wall using data measured in the field. The experimental results showed that the cross-sectional force and displacement of the high-strength bonded pile retaining wall were reduced by 13.6~19.7%, the shear force increased by 0.7~4.7%, and the bending moment increased by 4.5~8.8% relative to the values for the C.I.P retaining wall. Examination of the amount of subsidence in the ground around the excavation showed that the maximum settlement of the C.I.P retaining wall was 46.89 mm and that at the high-strength combined buried pile retaining wall was 39.37 mm. Overall, designing a high-strength combined embedded pile retaining wall by applying the maximum bending moment and shear force calculated using the elastic beam method to the site ground was shown to achieve the safety of all members, as member forces were generated within the elastic region.

본 연구에서는 고강도 결합 매입말뚝 흙막이 공법의 안정성을 검증하고 그에 따른 현장 적용성을 확인하고자 하였다. 따라서 C.I.P 흙막이 공법과 고강도 결합 매입말뚝 흙막이 공법을 수치해석으로 비교 ‧ 분석하였으며, 고강도 결합 매입말뚝 흙막이 공법이 적용된 현장의 계측 Data와 수치해석 결과를 비교 ‧ 분석하여 지반거동 및 고강도 결합 매입말뚝 흙막이 공법의 안정성 및 현장 적용성을 검증하고자 하였다. 실험결과, 단면력의 경우 고강도 결합 매입말뚝 흙막이벽이 C.I.P 흙막이벽보다 변위는 최소 13.6%~최대 19.7%가 감소하였고, 전단력은 최소 0.7%~최대 4.7% 정도 증가하였다. 또한 휨모멘트의 경우 최소 4.5%~최대 8.8%정도 증가하는 경향을 보였다. 굴착주변 지반의 침하량을 검토한 결과, C.I.P 흙막이벽이 최대 46.89 mm, 고강도 결합 매입말뚝 흙막이벽이 39.37 mm로 산정되었으며, 고강도 결합 매입말뚝이 C.I.P 흙막이벽에 비해 최대 침하량이 약 17% 정도 작게 산정되었다. 현장지반을 대상으로 탄소성보법에 의해 산정된 최대 휨모멘트와 전단력을 적용하여 고강도 결합 매입말뚝 흙막이벽체를 설계한 결과, 모두 탄성영역 내에서 부재력이 발생되어 안전한 것으로 나타났다.
