2. The site shown in the following figure was loaded with da = 10 TSM applied at Elevation (EL)= +2.0 m. A piezometer located in the underlying sand shows a constant piezometric water elevation (PWE) = -4.0 m during consolidation of the stiff clay that remains overconsolidated. The following data were obtained 128 days after the middle of the loading period: Settlement of the top surface of clay layer, S-0.055 m - 5.5 cm Piezometric water elevations (PWE) are as follows Piezometer Elevation PWE No. (m) (m) A -6.0 +6.60 B -8.0 +3.35 Note: both readings are consistent with Terzaghi's consolidation theory da = 10 TSM Elevation +2m Original ground surface Om Dense sand, 74 = 2.0 TCM $= 2.0 TCM -2m -4m Piezometer A Stiff saturated clay 24 = 2.0 TCM Constant m, and kv with depth -6m -8m Piezometer B - 10m Dense sand with pumping PWE --4.0m (a) Calculate the additional settlement that will occur due to primary consolidation. (b) Estimate the rate of seepage per unit area (i.e., Q/A) that exited through the clay prior to application of the load. 2.
