11.5 Liquefaction is a phenomenon in which the strength and stiffness of a soil is reduced by earthquake shaking. What soil type(s) are vulnerable to liquefaction? • Dense and dry sandy soil Loose, water-saturated sandy soil Clay . . Uncompacted (low-density) fill, having high water content Fractured rock

What is the typical saturated permeability values for sand, silt and clay?
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 level. The submerged unit weight and bulk unit weight of the sand layer are 15 kN/m³ and 20 kN/m³ respectively. The vertical stress increase at the centre of the clay layer is 100kPa due to the weight of the structure. Calculate the settlement of the structure due to primary consolidation. Take G =2.7.
If a clay layer is initially normally consolidated on site, which of the following processes or actions would lead to the clay layer becoming over-consolidated (select all that apply)? A.Construction of a building resting on a mat foundation on the ground surface B.Excavation of overlying soil C.Erosion of overlying soil D.Water table drawdown E.Demolition and removal of a building resting on the ground surface
Why does deposits of clay-mix soils do not experience liquefaction during earthquakes?
A) A soil mass above a certain depth becomes unstable when there is a negative effective stress at the depth (True or False) B) A soil’s effective stress is the sum of the soil’s total stress and its pore water pressure (True or False) C) The consolidation theory is usually applied to estimate a consolidation settlement for sandy soils (True or False)

4. (a) Time required for a 3m clay layer, sitting on bedrock, and overlain by a sand layer to fully consolidate is 4 years. What if the clay layer was on a sand layer or another stiff clay layer? Please explain (with reasoning) how the time required for the consolidation process to complete is likely to be affected in either case (no calculations required to be shown).
