For the soil profile shown below, calculate the final settlement due to the placement of the...
Two undisturbed clay samples were taken from the middle of the overconsolidated and normally consolidated clay layers in the soil profile shown. The water table is at the top of the overconsolidated clay layer. Consolidation tests were carried out on the two samples and the results are summarized in the table below. Assume that the bulk, dry, and saturated unit weights of the sand are 16 kN/m3, 16 kN/m3 and 19 kN/m3, respectively. The specific gravity of the clay soil...
A high-rise structure is to be built over the soil profile shown below. The proposed rectangular foundation footprint is 20 m x 40 m and is uniformly loaded with 800 kPa. A piezometer was installed in the ground directly below the center of the foundation at a depth of 10 m (below the ground surface) prior to construction to monitor pore water pressure. Using a unit weight of water equal to 10 kN/m], answer questions 6, 7, 8, 9, 10,...
1. An 8-m thick normally consolidated clay layer is doubly drained as shown below. (This means that a very pervious layer compared to the clay exists on top of and under the clay layer) The embankment applied an average vertical stress increase of 100 kPa to the clay layer. The water table is located at the mid depth of the sand layer. Assume the sand above the water table is dry 0 Pore water pressure, u (kPa) 20 40 60...
