Concept explainers

Sediment transport

Sediment transport or Soil transport is the movement of solid particles, usually due to the combination of gravitational forces acting on the sediment, and the movement of the liquid at which the sediment enters. Soil erosion occurs in natural systems where the particles are sandstones (sand, rocks), mud, or clay; the liquid is air, water, or ice; and the gravitational force that works to move particles to the landing surface. Sediment transportation or soil migration due to the movement of liquids occurs in rivers, lakes, lakes, oceans, and other bodies of water as a result of currents and waves. Transportation is also caused by glaciers as they flow, and to places on earth under the influence of wind. Soil erosion due to gravity alone is possible in most sloping areas, including hills, scarves, cliffs, and the continental shelf — the continental boundary of the slope.

A soil profile consists of 12 m of gravel overlying a clay layer of 3.5 m thickness,which in turn rests on a 4 m sand layer. The dry and saturated unit weights of thegravel are 17.5 kN/m3 and 20.5 kN/m3. Unit weights of the clay and the sand are20 kN/m3 and 19.5 kN/m3 respectively. Below the sand layer lies impermeablebedrock. If a wide excavation of 3 m depth is to be made in a relatively short time,draw the effective, total and pore pressure diagrams before and a long time afterthe excavation is made. Ground water table is 5 m below the ground surface.

A tank of total height 5 m is filled with sand of thickness 3.5 m having void ratio and specific gravity of 0.65 and 2.78, respectively. Remaining portion of tank is filled with water. The pressure head at the bottom of tank is 7.2 m. Assume unit weight of water is 10 kN/m³. The effective stress at a point 3 m below the top of the tank is kPa. (Round off to two decimal places).
A clay layer of 30 m thick with a unit weight of 20 kN/m3 overlies a sand layer. The groundwater table is at the ground surface initially. A 20 m deep excavation is made in the clay layer. Piezometric measurements show artesian pressure at the bottom of the clay layer, amounting to a water level of 8 m above the excavation base. Calculate the factor of safety against the bottom heave for the excavation.
