단섬유 보강된 다짐토의 강도특성과 보강 효과(지반공학)
Strength Characteristics and Reinforcing Effect of Compacted Short Fiber Reinforced Clay
초록
A series of consolidated undrained triaxial tests for compacted short fiber reinforced clay were performed to increase the field applications, e.g. retaining wall, waste landfill, soft ground etc. of soil admixtures mixed with short fiber. Kaolin clay and three types of fiber were selected. To acquire reliable length of fibers, an auto cutter was used and a helical mixer was also used to avoid floating of fibers during mixing soil and fibers. It is found that reinforcing effect by aspect ratio and mixing ratio of short fiber decreases as confining pressure is increased. Reinforcing effect has a maximum value at the aspect ratio of 120 and the fiber content of 0.6%∼1.2% and low confining pressure like 50kPa.
