A 5.00m clay overlain with a 5.00m sand. The sand has a specific gravity of 2.65 and a void ratio of 0.70. The clay has a saturated unit weight of 19.22kN/cub.m, a void ratio of 0.90 and a liquid limit of 60%. The water table is located 1.00m below the ground surface and the soil above the water table is 50% saturated. A load of 75kPa is distributed on top of the ground surface. What is the overburden pressure on the mid-height of the clay layer?
A 10-ft-thick clay layer is drained at the top and bottom. Its characteristics are Cvr = Cv (for vertical drainage) = 0.042 ft2/day, rw = 8 in., and de = 6 ft. Estimate the degree of consolidation of the clay layer caused by the combination of vertical and radial drainage at t = 0.2, 0.4, 0.8, and 1 year. Assume that the surcharge is applied instantaneously, and there is no smear.
Give the main reason/s for the following statements. (a) Overexcavation and replacement method is suitable for shallow ground improvement. (b) Punching failure through the replaced zone likely happen? (c) An increase of the replaced zone modulus can reduce the vertical stress applied on the top of the soft soil. (d) Granular columns likely bulge near the ground surface. (e) Geosynthetic encasement may be required in Granular columns
Q- If a soil has a voids ratio of 0.68 and water percolating through it has a discharge velocity of 1.35*10-2cm/s. Calculate its seepage velocity.
A soil formation is composed of 5m thick clay and 5m thick sand being sand above the clay. The groundwater table is located at 2m below the ground surface, assume E=6900kPa, If=0.79 and µ=0.2 a. A rigid column footing 1.2m in diameter is constructed. The load on the footings is 170kN. Determine the immediate settlement in mm. b. Calculate the primary compression index. c. Calculate the primary consolidation settlement of the normally consolidated clay layer if there is a surcharge of 40kpa acting on the ground surface. (neglect footings load) in mm.
For the first series of tests, no drainage of pore water occurs, either when the normal load is applied or during shearing (relating to clay’s very low coefficient of permeability). How does the “no drainage” control can be visualized?
need fast please A 4-meter clay layer (e = 0.95, Gs = 2.61, Cc = 0.335) is overlain with 4-meter-thick sand layer (e = 0.75, G = 2.88). The water table is at the interface of the sand and clay layer. If a 2-meter-thick land fill (γ = 17.39 kN/m3) is placed over the existing ground surface, compute the consolidation settlement (in mm.) of the clay layer. Hint: Use the land fill's resulting pressure on the ground surface as the stress increase. Round off to two decimal places.
A uniform soil has 10% passing the 0.425 mm sieve.a. What type of soil is it?b. Estimate the permeability.c. If the average pore/void diameter is 20% of the effective size, find the height of thecapillary rise.d. Would this soil cause serious frost heaving? Why?
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. Whatwill be the change in the effective stress on top of the softclay layer?
