초록

동상으로 인한 구조물의 피해를 방지하고자 세계 100여개의 국가에서는 토양의 동상민감성을 판정하는 실내실험법에 대해 연구를 진행하였다. 미국과 일본은 알래스카와 홋카이도와 같은 동토지역을 포함하고 있어 동상에 대한 연구가 활발히 진행되었으며, 연구 결과와 현장 적용을 통해 동상민감성 판정 표준 실험법과 기준을 제시하고 있다. 그러나 실험 방법이 복잡하고 공학적인 해설이 부족하며, 결과 분석에 대한 논리가 모호한 부분이 여전히 존재하고 있다. 본 논문에서는 이러한 미국 ASTM(American Society for Testing and Materials)과 일본 JGS(Japanese Geotechnical Society)의 동상 실험법을 동상 실험에 미치는 온도조건, 시료크기, 동결방향, 배수조건 등을 고려하여 면밀히 비교 분석하고, 지금까지 연구결과를 종합하여 향후 국제적인 연구동향에 부합하는 국내 동상민감성 판정 실험법과 기준의 방향을 제시하고자 한다.

Over 100 countries have conducted research on experimental testing methods to assess the frost susceptibility of soils. This study aims to prevent structural damage caused by frost heave. Notably, the United States and Japan, which encompass cold regions such as Alaska and Hokkaido, have actively pursued frost heave research. Through laboratory investigations and field applications, standard testing methods and criteria for evaluating frost susceptibility have been established. However, these methods are complex and their engineering explanations are vague. This study closely compares and analyzes the frost-susceptibility testing methods proposed by ASTM and JGS, considering temperature conditions, specimen size, freezing direction, and drainage conditions. By conducting this comparative analysis, this study aims to shed light on the similarities and differences between the two methods. Furthermore, based on the findings, this study proposes future research guidance for refining frost-susceptibility testing methods and criteria.
