입자파쇄에 따른 화강토의 전단강도 변화 = Study on Shear Strength Characteristics of Weathering Granite Soil for Particle-Crushing

다국어 초록 (Multilingual Abstract)

Weathering granite soil is typical residual soil in Korea and it is known as a problematic soil because the characteristic of strength is changed by the degree of weathered. The aim of this study is to evaluate its characteristic of strength for particle-crushing.
Weathering granite soil crushed particles by the drop down from 2 meter height 30, 50, 100, 150, 200 times. Each of samples accomplished the CU trixial compression test under the various confining pressure. And the undisturbed sample accomplished the CU, CD triaxial compression test. As the results of the study, The number of the drop down effect on the particle size distribution and the shear strength.
