An Abutment Wall 6 M High Is Reinforced With Sheet Reinforcement At Vertical Spacings Of 0 5 M The Angle Of Friction Be 1 (73.91 KiB) Viewed 48 times

An abutment wall 6 m high is reinforced with sheet reinforcement at vertical spacings of 0.5 m. The angle of friction between the sheet and the fill is 22º. The creep limited tensile strength of the reinforcement is 30 kN/m and the interaction coefficient for the soil-reinforcement interface a' is 0.9. The weight density of the frictional fill is 19 kN/m3 and its peak angle of friction is 30° with c' assumed to be zero. The length of the reinforcement is taken initially as 0.7H = 0.7 x 6m = 4.2 m Carry out a calculation to check on the local stability of the reinforcement layer at 1 m below the top of the reinforced soil block for tensile rupture and pull out resistance. 0.5 m 6 m
