A structure is built on a normally consolidated clay of thickness of H(m), where H is the last digit of your student identity number (SID). If the last digit of your SID is zero, take H = 10m. The normally consolidated clay has a natural moisture content of 45% and a Liquid limit of 50%. Ground investigation results show that the clay is overlain by a 15m layer of sand, and the ground water table is at 10m below ground

A certain saturated sand (S = 100%) has a moisture content of 27.9% and a specific gravity of solids of 2.61. It also has a maximum index void ratio of 0.90 and a minimum index void ratio of 0.33. Compute its relative density and classify its consistency. (Table on the right) Solution: Given the values of mmoisture content, specific gravity and degree of saturation, the void ratio can be estiamted as: e = Thus the relative density is found to be Dr = • According to the table, the soil is classified as %; soil.
