Abstract

Shaking table tests to investigate the dynamic friction behavior of interfaces between dense dry granular soils and construction material(concrete) were performed and the results are reported. The results show the variation of dynamic interface friction coefficients between dense dry granular soils and construction material was small in the sliding velocity range employed in this study. It was also observed that dynamic interface friction coefficients decreased as mean grain sizes of granular soils increased. These coefficients were compared with the friction coefficients obtained from the peak internal friction angles of the same granular soils by plane strain compression tests.

조밀한 건조조립토와 건설재료(콘크리트재)사이의 경계에서의 동마찰계수를 구하기 위하여 진동대를 사용하여 동적직접전단시험을 실시하였다. 조밀한 건조조립토와 건설재료사이의 동마찰계수는 본 연구에서 고려한 미끄러짐 속도의 범위안에서는 크게 변하지 않음을 알 수 있었다. 그리고 동마찰계수는 조립토의 평균입경이 증가함에 따라 감소하였고, 이에 대한 관계식을 제안하였다. 또한 이 계수를 같은 조립토에 대하여 실시한 평면변형률시험으로 얻어진 내부마찰각으로부터의 마찰계수와 비교하였다.
