You are evaluating the geotechnical characteristics of a Miami site for a proposed office building. Subsurface investigation showed that the site consists of the following layers: (1) a 5-ft sandy laver with a unit weight of 100 pcf (2) a 10-ft silty sand layer with a saturated unit weight of 115 pcf. (3) a 20-ft saturated clay layer with a unit weight of 118 pef, void ratio of 0.85, and underlain by gravels. The site seemed to have strong potential for undergoing consolidation settlement. Therefore, you collected samples from the clay ayer and performed a consolidation test. The pre-consolidation pressure for the clay was known to be 1.0 tons/t. The ground water table is at the level of the second sand layer. Some of the data points from the test are as follows: Effective Consolidation Pressure(tsf Void Ratio 0.2 0.5 3.0 1.03 1.01 0.85 0.75 *)ウ To expedite the consolidation process and achieve stability, a fill material was brought in from another location and placed on the site. This fill material was a sandy soil with a unit weight of 110 pcf and its thickness was 5-ft. Perform the following tasks: Draw a schematic of the subsurface conditions including all the properties. Draw the distribution of total stress, pore water pressure and effective stresses. eCalculate the total consolidation settlement due to the load applied by the filil. А:/son If the ground water table drops 4 ft., what effect will it have on the settlement ? . Justify your answer.
