Soil Mechanics Problem 2 (26 points) Results from a standard Proctor compaction test yield an Optimum Moisture Content (OMC) of 12% and a maximum dry unit weight of 18.1 kN/m. Given this information, address the following questions. a) The soil was used to construct an embankment on a construction site. A sand cone test indicated that a layer of the compacted fill had a total unit weight of 19.8 kN/m3 and a moisture content of 11%. Specifications call for the...
(4). (8 pts). A soil profile is shown in below Figure. A uniformly distributed load Ao is applied at the surface of soil. Given the preconsolidation pressure is between swell index and compression index is: C C/6. The unit weight of water is: -9.38 kN/m. If U-98% we regard it as a completion of primary consolidation. We have taken the clay sample and done the Atterberg Limit test. For the liquid limit test, the result is as below. Please ơ'-926...
