The following figure show the relationship between the voids ratio and effective stress for a soil sample collected from the mid depth of a 6 m thick clay layer. The Cc and Cr values have been determined to be 0.3 and 0.04 respectively. For the given information: If the current effective stress at the mid depth is 70 kPa, calculate the ultimate consolidation settlement when the effective stress at mid depth increases by 10 kPa due to an applied load. If the coefficient of consolidation is 0.555 m2/s and the clay layer is single drained, calculate the time taken to reach 45% consolidation.
Laboratory tests on a 25-mm-thick clay specimen drained at the top and bot-tom show that 50% consolidation takes place in 8.5 min.a. How long will it take for a similar clay layer in the field, 3.2 m thick anddrained at the top only, to undergo 50% consolidation?b. Find the time required for the clay layer in the field described in part (a)to reach 65% consolidation.
The figure below shows the soil profile at a site where you plan to lower the water table. You have results from two consolidation tests, one from the upper 12 ft thick overconsolidated crust, and another from the lower 40 ft thick normally consolidated zone. You plan to lower the water table from its current 12 ft depth to 25 ft below ground surface. The consolidation properties for each layer are shown. (Assume that changes in GWT do not affect γt of clay). a. Compute the σ′v in the middle of each layer before and after the water table is lowered b. Determine the total settlement that will result from lowering the water table
In a consolidation test, a fully saturated clay sample was subjected to a load of 500 kN/m2. After 12 hours, the average pore pressure was found to be 200 kN/m2. The time (in hours, rounded off to two decimal places) required for 50% consolidation to take place is
