제주도 현무암의 점착력과 내부 마찰각 = Cohesion and Internal Friction Angle of Basalts in Jeju Island

다국어 초록 (Multilingual Abstract)

Volcanic rocks in Jeju Island indicate the differences in geological and mechanical characteristics from region to region,and have vesicular structure caused by various environmental factors. In this study, triaxial compressive strength testswere conducted for intact rocks sampled in northeastern onshore and offshore, southeastern offshore and northwesternoffshore of Jeju Island. The estimated cohesion and internal friction angle from the results of triaxial compression testswere compared and analyzed with absorption, a parameter representing the vesicular properties of basalts in Jeju Island.
As a result, it was found that the relationship between cohesion and absorption could be classified clearly, consideringtwo different linear relationships in bulk specific gravity and absorption. As the absorption increases, the cohesiondecreases exponentially. In addition, the internal friction angle decreases almost linearly with increasing in the absorption,regardless of the relationships in bulk specific gravity and absorption.
