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...

20-ft thick fill is planned to be placed at a construction site. Ground settlement is of concern due to high compressibility of the clay layer. A consolidation test was performed on a sample collected from the center of the 15-ft thick clay layer. On the following page, e-logp curve obtained from the test is included. Estimate ground settlement based on the information provided. Hint: Don't forget to correct the curve for field conditions. Ifơ0 is within 10%...
