Question

Discuss following questions:

1) The effect of water table in a sheet pile wall

2) Effect of dredge line in a sheet pile wall

3) Effect of angle of friction between wall and sand in a sheet pile wall

4) Effect of diameter in a Caisson pile

5) Effect of surcharge in a retaining wall

Answer #1

1.Water table indicates the property of ground

The water table is high then it is soft ground

2.Depth of plastic zone is depends upon dredge line.The depth below this line is called Depth of plastic zone

3.The friction angle increases the bending moment, deflection and settlement adjacent to sheet pile wall decrease.

4.The Caisson pile have daimeter range from 18-144 inches.These are used to sustain high axial and lateral loads.And moreover it is cost effective.

5.The surcharge will exert some pressure on the retaining wall

And the pressure is more at near the surface of the wall and gets low with increase in height of wall.

A
concrete pile 1-m diameter is driven 15-m in dense sand with
following properties: γ=17.5 kN/m3, φ=30o, K=0.90 and FS=3. Water
is 5-m below the ground surface. Use typical values for any missing
data. What is the design load for this pile?

ft). - Backfill: unit weight 110 pcf, internal friction angle 33° -
Metal strip reinforcement: vertical spacing 3 ft, horizontal
spacing 4 ft, width of reinforcement 5”, yield stress of
reinforcement 35,000 psi, friction angle between the soil and
reinforcement is 24°, FS pullout failure = 2, FS tensile failure =2
