전단마찰시험에 의한 섬유혼합토와 지오그리드 사이의 마찰 특성 평가
Friction Properties between Fiber-Mixed Soil and Geogrid by Shear Friction Tests
초록
The shear friction tests using large direct shear test units were performed to evaluate the friction properties of fiber-mixed soil. The used materials and test conditions were flowing. Soils : SM and ML; mixing fibers : three types of polypropylene fibers(net type 38mm and 60mm, and line type 60mm), reinforcement : geogrid; mixing ratio:0.2% and 0.3%; degree of compaction : 85% and 95%. In the test results, the reinforcing effect of fiber mixed soil was confirmed.
