The soil profile at a site consists of 10 m of gravelly sandunderlain by a soft clay layer. The water table lies 1 m belowthe ground level. The moist and saturated unit weights of thegravelly sand are 17.0 kN/m3 and 20.0 kN/m3, respectively.Due to some ongoing construction work, it is proposed tolower the water table to 3 m below the ground level.
The soil profile shown below is subjected to a uniformly distributed load (UDL) on ground surface of 600 kN/m². The underground soil consist of two normally consolidated clay (N.C.C.) layers, and between them one sand layer with properties as shown on the figure.
A soil profile is shown in the figure below. A uniformly distributed load, Ao , is applied at the ground surface equal to 100 kPa.

A soil profile consists of 3m of clean sand (γ=18kN/m³) over 10m of silt (γ=17kN/m³, kv=1 x 10-8m/s) over 12m of clay (γ=17kN/m³, kv=4 x 10-9m/s) over gravel. Piezometers installed at middepth of the sult later and at the top of the gravel layer measure, respectively, piezometric heads of 4m and 3m.
Transcribed Image Text: Using the figure below, which soil profile is more developed? Why? Ah Bw Bt • In the 2nd soil profile, what do you think were the dominant processes that led to the development of the soil? Explain. Based on the soil horizons present, which soil profile is more fertile? Explain.
Problem 4: The soil profile consist of a dry sand 5 m thick which overlies a layer of clay having thickness of 7 m. Dry sand has Gs = 2.7 and e = 0.40. While clay has Gs = 2.75 and e = 0.92. Ground water table is located at the interface of the sand and clay. 1. Compute the bottom of the clay layer total, pore and effective stresses. 2.
A constant head of 470mm is maintained across the soil sample. The porosity for Soil I is 0.5 and the value of k is 5*10^-3 cm/s. The porosity for Soil II is 0.55 and the value of k is 4.2*10^-2 cm/s. The porosity for Soil III is 0.35 and the value of k is 3.69*10^-4 cm/s. The hydraulic conductivities are measured in the direction of the flow.

Determine the effective stress at pt. A Determine the effective stress at pt. B. Determine the effective stress at pt. C Please answer this asap. For upvote.
A soil profile consists of a sand layer 2m thick, whose top is the ground surface, and a clay layer 3m thick with an impermeable boundary located at its base. The ground water table is at the ground surface. A widespread load of 150kPa is applied at the ground surface. Assume that the soil is in a normally consolidated state.
