A rigid smooth retaining wall of height 7 m with vertical back face retains saturated clay as backfill. The saturated unit weight and undrained cohesion of the backfill are 17.2kN/m3 and 20 kPa, respectively. The difference in the active lateral forces on the wall (in KN per meter length of wall up to two decimal places), before and after the occurrence of tension cracks is 46.6

Answer» A rigid smooth retaining wall of height 7 m with vertical back face retains saturated clay as backfill. The saturated unit weight and undrained cohesion of the backfill are $17.2 k N / m^{3}$ and 20 kPa, respectively. The difference in the active lateral forces on the wall (in KN per meter length of wall up to two decimal places), before and after the occurrence of tension cracks is 46.6

A timber pile of length 8m and diameter of 0.2m is driven with a 20 kN drop hammer, falling freely from a height of 1.5m. The total penetration of the Pile in the last 5 blows is 40mm. Use the engineering news record expression. Assume a factor of safety of 6 and empirical factor (allowing reducing in the theoretical set, due to energy losses) of 2.5 cm. The safe load carrying capacity Of the pile (in kN, round off to 2 decimal places) is151.515
