Reinforcement Effect Comparison of Reinforced Clayey Soil with Various Geotextile

각종 지오텍스타일 보강재에 의한 보강점성토의 보강효과 비교

Recently, research of reinforcement mechanism in a sense of soil mechanics has been under way by many researchers with developing various kinds of geoteutiles. But it must be consider that reinforcement effect largely depends on used geotextile even if it is used on same in-site condition. As a matter of fact it is not necessarily that reinforcement effect appears in all the case of reinforced soil construction. It means that appropriate geotextile coincided with the intention has to be selected and adequate examination is needed. In this study, reinforcement effect with various kinds of geotextiles are compared through a series of direct shear tests. Based on the test results, shear strength characteristics and reinforced effects are investigated quantitatively and qualitatively considering the confining stress, reinforcement characteristics and number of reinforcement.
