A soil profile is shown in Figure Q3(b)(i). The groundwater level is located on the ground surface. The sand layer is under artesian pressure where the excess pore water pressure is 40 kN/m^2. (i) Calculate the total vertical stress, pore water pressure and effective vertical stress at the base of each layer. (ii)Determine the increment of the effective stress at the base of sand layer if the 1.5m height fill will be imposed on the ground surface. Note that, the density of the fill material is 1750 kg/m^3. (iii) The excavation will be made in the clay layer for the basement construction. Evaluate the stability of the soil from boiling or quick condition. The depth of the excavation is shown in Figure Q3(b)(ii). (iv)Propose the maximum depth of cut that can be made to avoid boiling or quick condition.
A dilatometer test was conducted in a sand deposit ata depth of 6 m. The groundwater table was located at a depth of 2 m below the ground surface. Given, for the sand: 3.29 - 14.5 kN/m3 and Yat 19.8 kN/m3. The contact stress during the test was 260 kN/m2. Estimate the soil friction angle, ф".

a. A vane shear test was conducted in a saturated clay. Theheight and diameter of the rectangular vane were 4 in.and 2 in., respectively. During the test, the maximumtorque applied was 230 lb ? in. Determine the undrainedshear strength of the clay.b. The clay soil described in part (a) has a liquid limit of58 and a plastic limit of 29. What would be the correctedundrained shear strength of the clay for design purposes?Use Bjerrum’s relationship for l [Eq. (3.40a)]. Determine the overconsolidation ratiofor the clay. Use Eqs. (3.42) and (3.45). Use s9o 5 1340 lb/ft2.
Figure Q1(c) shows the soil profile with groundwater table is 6 m from thesurface impermeable layer. Calculate the total stress, pore water pressureand effectives tress at points D.
Homeworks of chapter 5 1. Figure below shows the soil proile at a site for a proposed building. The soil is a homogeneous, poorly graded sand. Determine the increase in vertical effective stress at which a soil element at a depth of 3 m, under the center of the building, will fail if the increase in lateral effective stress is 20% of the increase in vertical effective stress. The coefi- cient of lateral earth pressure at rest, Kp, is 0.5. Assume all stresses are principal stresses. Ground surface 1m Ya = 18 kN/m - 30 2 m .3

Effective Stress in Soil Problem 1. The water table in a certain deposit of soil is at a depth of 2m below the ground surface. The soil consists of clay up to depth of 4m from the ground and below which lies sand. The clay soil is saturated even above the water table: Clay strata: ? = 30%,?? = 2.72 Sandy Strata: ? = 26%, ?? = 2.64 1. Compute the total pressure. 2. Compute the pore water pressure. 3. Compute the effective stress pressure at a depth of 8m below the ground surface
solve the problem 11-29 as shown in the figure.
