Abstract
본 논문에서는 이중보온관의 다짐시공 중 안정성 평가 및 되메움 대체재료 제시를 위하여 현장시험을 수행하였다. 현장시험 시 사용된 되메움 재료는 기존 되메움 재료인 중사와 되메움 대체재료 평가를 위한 자연모래 2종(세사, 왕사)과 부순모래, 자갈 2종(10mm, 20mm)을 사용하였다. 현장시험은 되메움재료 별 이중보온관 토압 및 변형, 외관손상 등의 거동특성 평가를 위하여 수행하였다. 연구결과에 따르면, 부순모래는 5종의 되메움 대체재료 별 평가결과 이중보온관에 미치는공학적 특성 및 재료의 수급 측면에 있어 기존 중사를 이용하는 이중보온관 되메움재의 대체재료로 가장 합리적인 재료로평가되었다;In this study, field tests were performed to evaluate the stability of pre-insulated pipe during the compaction operation and to recommend an alternative backfill material. Three types of natural sand (fine-grained and medium-grained, coarse-grained sand), crushed sand and two types of gravel (10 mm, 20 mm) were used as backfill material in the field tests. Field tests were performed to determine the behavior (earth-pressure and deformation, installation damage) of the pre-insulated pipe due to variation of different types of backfill material. Based on the evaluation and comparison of field test results, it was determined that crushed sand is the most suitable back-fill material that can be used as an alternative for medium grained sand for pre-insulated pipes with respect to the engineering behavior and material supply.
