92 MSETTLE USER MANUAL should be chosen equal to the initial position of the horizontal drains, in this case at RL <-2.2> m as shown in Figure 4-35. Figure 4-35 – Vertical Drains window, Enforced Dewatering input (Tutorial-2e) 48. Perform a new calculation in the Start Calculation window. 49. Verify that the residual settlement after 900 days is 0.140 m for vertical 4. 50. View the excess head versus time at vertical 4, RL-4.875 m (Figure 4-36). Note that the excess head is reduced considerably during enforced dewatering. Figure 4-36 – Time-History window, Excess head vs. Time in vertical 4 at RL-4.875 m, with enforced dewatering (Tutorial-2e) 51. View also the effective stress versus time at vertical 4, RL-4.875 m (Figure 4-37). Before 438 days, the effective stress increases continuously, due to still
