1. A soil profile for an office building foundation is on a sand layer of 10.4 meters, which is located above a normal consolidated sand soil layer with a thickness of 2 meters. Under the clay layer there is coarse sand. The groundwater level is 3 meters below ground level. The sand pore number is 0.76 and the clay moisture content is 43%. The building will exert a pressure of 140 kPa on the clay, so that the clay will undergo primary consolidation. Assume that if it rains there can be a rise in the groundwater level to the surface. So the sand can become saturated with water. Cc = 0.3 and Gs = 2.7. %3D

Question
Transcribed Image Text:1. A soil profile for an office building foundation is on a sand layer of 10.4 meters, which is
located above a normal consolidated sand soil layer with a thickness of 2 meters.
Under the clay layer there is coarse sand. The groundwater level is 3 meters below ground
level. The sand pore number is 0.76 and the clay moisture content is 43%. The building will
exert a pressure of 140 kPa on the clay, so that the clay will undergo primary consolidation.
Assume that if it rains there can be a rise in the groundwater level to the surface. So the
sand can become saturated with water. Cc = 0.3 and Gs = 2.7.
