Question

Question 5 (20 marks): An anchored sheet-pile wall, showr the having t 1.25 m and anhe soil has a bulk density of 1900 kg/m'. a of shearing resistance of 30°. The anchor tie rods l length of 9.75 m. The soil has at own in Figure 4, retains soil of height 6 m, the piles h are at 1.25 m below the surface of the soil. a) Find the active thrust on the piling in kN per hor b) Fi ごの rust on the piling in kN per horizontal meter nd the tension in the tie rods if they are spaced at 5 m centers. 30 1-25 m 1,900 3-25m 1-25m ろ re 4: The anchored sheet-pile wall.

Answer 1

P-a = (1/2 k_a middot r middot H62) B P_a = 1/2(1 - sin 30/1 + sin 30)(19kn/m^3) v(9.75)^2 * 1 P_a = 301 kN/m P_p 1/2 middot Kp middot r middot H62 P_p = 1/2(1 + sin 30/ 1 + sin 30)(19(3.75)^2 P_p = 4..78 kN/m Sigma m_bottom = 0 T(8.5) + 400.78(1.25) - 301(3.25) = 0 T = 56.15 kN/m T = 56.15 * 5m T = 280.75kN
