What is the minimum factor of safety to be used to determine the allowable geotechnical capacity of a pile with respect to failure?
Design values for allowable soil bearing pressures given by the geotechnical engineer should consider allowable settlement criteria of the structure, and include a factor of safety of at least 1.5 to 2.0.
What is allowable soil bearing pressure?
Allowable bearing pressure shall be considered to be the pressure at the base of a foundation in excess of the stabilized overburden pressure existing at the same level prior to construction operations.
Does bearing capacity increase with depth?
They found that as depth of foundation increases, bearing capacity increases. They found that these is increased in dry density and decrease in optimum moisture content. They also studied the effect of depth of footing using geotextile reinforcement.
How do you calculate soil bearing capacity?
Bearing capacity is one method of measuring this strength. Researchers can calculate the bearing capacity of soil by determining the limit of contact pressure between the soil and the material placed on it.
How do you calculate the safe load capacity of a pile?
Step 2: compute the ultimate end bearing capacity (acting as individual piles). Ultimate end bearing capacity in clay = Nc × C × pile tip area (Nc = 9). Ultimate end bearing capacity in soft clay = 9 × 120 × π × diameter2/4 = 848.2 lbs/per pile. Total ultimate bearing capacity per pile = 76,920 + 848.2 = 77,768 lbs.
How can you increase the safe bearing capacity of soil?
The following techniques can be used for improving bearing capacity of soil as per the site condition.
- Increasing depth of foundation.
- Draining the soil.
- Compacting the soil.
- Confining the soil.
- Replacing the poor soil.
- Using grouting material.
- Stabilizing the soil with chemicals.
How do you test the safe bearing capacity of soil?
Safe bearing capacity: The maximum intensity of loading that the soil will safely carry without risk of shear failure is called safe bearing capacity of soil. This is obtained by dividing the ultimate bearing capacity by a certain factor of safety, and it is the value which is used in the design of foundation.
How can I strengthen my existing foundation?
Widening and strengthening of existing foundations may be carried out by constructing a concrete jacket to the existing footings. The new jacket should be properly anchored to the existing footing and column neck in order to guarantee proper transfer of loads.
