An excavation is to be made in a layer of clay which is 10 m thick and underlain by a sandstone formation. The water table is at the ground surface and the saturated unit weight of clay is 21 kN/m³. The water level in a piezometer installed in the sandstone rises 2.5 m above the ground surface. Draw a representative sketch of the problem and calculate the depth of excavation that can be reached without an upheave of the bottom of excavation.

geotechnical engineering question
An exploratory drill hole was made in a stiff saturated clay having a moisture content of 29% and G, = 2.68 (Figure 9.27). The sand layer underlying the clay was observed to be under artesian pressure. Water in the drill hole rose to a height of 6 m above the top of the sand layer. a. If an open excavation is to be made in the clay, determine the safe depth of excavation before the bottom heaves. b. How much is the pressure at the interface of the clay and sand? c. If a factor of safety of 2.0 is to be ensured, how deep should be the excavation from the ground surface?

9.4 An exploratory drill hole was made in a stiff saturated clay (see Figure 9.9). The sand layer underlying the clay was observed to be under artesian pressure. Water in the drill hole rose to a height of 4 m above the top of the sand layer. If an open excavation is to be made in the clay, how deep can the excavation proceed before the bottom heaves?

A layer of fine sand exists over a stratum of impervious rock. The sand layer is 6.25m thick. The site is flooded and the water surface is 1.25m above the surface of the sand. It is proposed to excavate a very wide ditch through the site and to remove sand to a depth of 2.5m below the existing surface of the sand. One side of the excavation is to be supported by sheet piling driven to a depth of 4.4m below the existing surface of the sand. Draw a flow net and determine the seepage in m³/min per m length for the sand with a permeability of 0.18m/sec.
Q1 The two-way drainage clay layer of 6m thick, how long will it take for 75% consolidation to be over in the field? Given: cy= 0.24 cm²/min.
Time left 1:24:08 An excavation is to be performed in a stratum of clay, 9 m thick, underlain by a bed of sand. In a trial bore hole, the ground-water is observed to rise up to an elevation 3 m below ground surface.Find the depth of which the excavation can be safely carried out without the bottom becoming unstable under uplift pressure of ground-water. The specific gravity of clay particles is 2.70 andthe void ratio is 0.70. If the excavation is to be safely carried to a depth of 7 m, how much should the water table be lowered in the vicinity of the trench ? O a. 6 m O b. 9 m C. O c. 10 m O d. 8 m SHOT ON POCO F3
