Abstract

Structural instability and damage are caused by frost heave during the winter when atmospheric temperature maintains below $0^{\circ}C$. Frost heave is the most representative engineering characteristics of frozen ground and there are various frost susceptibility criteria. Frost susceptibility criteria can be roughly divided into three categories. First, frost susceptibility is determined from particle size distribution, which is practically useful and many countries are adopting. In this paper, several particle size distributions (PSDs) are applied to the frost susceptibility criteria but PSD seems to be not enough to determine whether soils are frost susceptible. Second, it is judged from laboratory frost heave testing results. Laboratory frost heave tests were performed with newly developed thermal controlled triaxial cell and the reliability of frost susceptibility criteria is evaluated. New testing apparatus and method are suitable to meet the existing frost susceptibility criteria. Third, it is compositive frost susceptibility criteria envelope including the particle size distribution, soil classification, and frost heave test. The compositive frost susceptibility criteria envelope should be supplemented based on additional data on various soil types.

구조물은 영하의 온도가 유지되는 겨울철에 동상으로 인해 크고 작은 피해가 발생한다. 동상은 동토지반의 가장 대표적인 공학적 특성으로 다양한 동상민감성 판정법이 존재한다. 동상민감성 판정법은 크게 3가지로 분류할 수 있다. 첫 번째 동상민감성은 입도분포를 이용하여 결정된다. 많은 국가들이 지반의 입도분포를 이용해 비교적 간편한 동상민감성 판정법을 현장에 적용하고 있다. 그러나 본 논문에서 몇 가지 시료의 입도분포를 이용해 동상민감성 판정 기준에 적용한 결과에 따르면 입도분포로 토질의 동상민감성을 판정하기에는 다소 무리가 있다. 두 번째로는 동상시험에 의한 동상민감성 판정법이다. 새롭게 개발된 온도제어형 삼축셀을 이용한 동상 실내시험을 통해 동상민감성 기준 신뢰성을 분석하였다. 새롭게 개발된 장비와 시험방법은 기존에 제시하고 있는 동상민감성 판정 기준을 충족하는 것으로 판단되었다. 세 번째로는 복합적인 동상민감성 판정법으로 흙의 입도분포, 분류, 그리고 동상시험을 고려한 복합적인 동상민감성 판정 기준 그래프를 제시하고 있다. 본 논문에서 몇 가지 시료에 대해 복합적인 동상민감성 판정 기준에 적용한 결과 다양한 토질에 대한 추가적인 데이터를 바탕으로 복합적인 동상민감성 판정 그래프를 보완해야 할 것으로 판단되었다.
