FPF(Fibrillated Polypropylene Fiber)보강 성토재료의 강도 특성에 관한 연구
Characteristics of Soils Reinforced by FPF(Fibrillated Polypropylene Fiber)
초록
This study was to analyze characteristics of soils reinforced by FPF(Fibrillated Polypropylene Fiber). Laboratory test, model test and field tests were performed on soils reinforced by fibers, to evaluate the shear strength characteristics. For the silty sand, clayey sand and silty clay, the influence of fiber shape, fiber length and fiber content were evaluated from compaction test, direct shear test, uniaxial test, california bearing ratio(CBR) test. Fibrillated type fiber, 5cm long with a content of 0.5% shows 5∼30% increase of friction angle and 7∼55 percent increase of CBR value.
