A soil profile in the "at rest" condition consists of an 8-foot thick surface of silty sand (Layer 1), a 16-foot thivh middle layer of sandy silt (Layer 2), and a 16-foot thich base layer of silty gravel (Layer 3). All soil layers are normally consolidated. The moist and saturated unit weights of these three materials are defined in Table 1. Determine the total vertical, pore pressure, effective vertical, effective horizontal, and total horizontal stress distributions associated with each of the four potential groundwater conditions defined in Table 2
