碩士 === 國立成功大學 === 土木工程學系碩博士班 === 96 === A series of tilting test on reinforced model slope backfilled withregularly packed 1.96mm-diameter steel rods and mixed 1.96mm &1mm (2:1) steel rods were performed to investigate the relativeimportance of facing rigidity , backfilled well or fail and reinforcement stiffness for the pseudo-static seismic stability of reinforced slope. Aluminum full-high panel with a wide range of bending rigidities andreinforcing materials with significantly different tensile stiffness wereused in the tests to investigate their effect on the ultimate tilting angles (or pseudo-static-based critical seismic coefficient) of the reinforcedmodel slopes. It was found that , of the factors investigated , the backfill frictionangle of the reinforcing materials and reinforcement quantity plays anessential role in the pseudo-static seismic stability of the walls.When the backfill friction angle of the reinforced model slops was too low ,increasing the facing rigidity or tensilesstiffness of the reinforcementresulted in a negligible effect on the ultimate tilting angle of the reiniforced slopes. Increasing the ratio of reinforcement quantity from 3to 5 provided a substantial increase inθ,regardless of the tensile stiffnessand facing thickness investigated in the study.The effect is a promising way of increasing the pseudo-static seismic stability of reinforced.
