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.

4.- A retaining wall with a vertical back is 8 m high. The volumetric weight of the 3 m fill surfaces is y = 1.75 ton/m3 and the angle of resistance is $ = 30°; for the 5m remaining fill the values are y = 1.85 ton/m3 and angle of internal friction = 35°. Also there is an overload on the horizontal surface of the landfill equivalent to 1.2 ton/m2, Evenly distributed. Find the magnitude and point of application of the thrust per meter of Wall. A) If the fill is well drained B) If the fill becomes saturated after a storm (assume for this case that the weights saturated values of the two strata are 1.9 and 2.0 ton/m3 respectively) q= 1.2 ton/m2 ↓↓↓↓ Y = 1.75 ton/m3 $ = 30° Y $ = 35° 1.85 ton/m3 H1 = 3.0 m H2 = 5.0 m
The site soil consists of loose sand that are dry within the top 3 m and saturated below. The present blow counts ranging between 2 and 10. Due to concerns regarding liquefaction dynamic compaction is proposed. The soil should be improved to a depth of 10 m. A 20-ton tamper with a diameter of 1.5 m and a height of 1.5 m is available. Assume a square pattern. More than one pass may be required. Estimate: 1. The required drop height 2. Spacing of the drops 3. Number of drops required 4. Number of passes required 5. SPT blow counts after improvement, and 6. Settlement.
For a clay layer with cv of 8x10-8 m2/sec and drainage path length of 6m with two way drainage and a total consolidation settlement of 0.52m, find the time for the clay to settle 0.25m.
What is the area of cut in square metre? what is the average cut in metres? what is the volume of cut in cubic metres? what is the area of the fill in metre square? what is the average fill? what is volume of full in cubic metres?

Known: B = 1m, L = 2m, Q = 100kN Estimate the consolidation settlement and How long will it take to reach 90% consolidation?
Estimate the total consolidation settlement (primary & secondary) after 2 years and 3 months after the completion of primary consolidation settlement of an over consolidated clay layer under the bridge pier as shown below. The pier's dimensions are (2 m x 3 m). Use Yw= 10 kN/m³ and note that the time for completion the primary consolidation is 3 years. | Qo= 960 kN G.W.L 1m Sand Ya=16.5 kN/m 2 m Ysat = 18 kN/m³ Silty Sand Ya=17.5 kN/m 3 m Ysat = 18.5 kN/m3 Clay Ya=20 kN/m , Ysat = 21 kN/m3 e, = 0.6 , Ae=0.04 , o= 78.3 kN/m2 4 m Cc= 0.4, Cs= 0.1, Ca= 0.02
ssion begins when the primary consolidation ends. B. The soil from a borrow area is excavated and used in a compacted fill for an embankment. The void ratio at the borrow area and the compacted fill are 0.96 and 0.62, respectively. What would be the volume of the excavation in the borrow area to construct 200,000 m3 of compacted fill? Q2:
6.5 The sides of an excavation 3.0m deep in sand are to be supported by a cantilever sheet pile wall. The water table is 1.5 m below the bottom of the excavation. The sand has a saturated unit weight of 20 kN/m³, a unit weight above the water table of 17 kN/m³ and the characteristic value of o' is 36°. Using the traditional method, determine the required depth of embedment of the piling below the bottom of the excavation to give a factor of safety of 2.0 with respect to passive resistance. M
