Introduction of End Bearing Piles

An end bearing pile is a deep foundation element used to support loads by transferring them to a competent stratum at significant depth below the ground surface. They are used when skin friction along the length of the shaft cannot be mobilized to support the load or when the soil at the toe of the pile is too weak to support the load. End bearing piles are typically driven or drilled into the ground until they reach the required depth and then grouted in place.

Determination of Bearing Capacity of End Bearing Piles

  • Bearing capacity is the ability of soil to support the loads applied to it
  • The bearing capacity of end bearing piles is the capacity of the piles to carry the loads applied to them without failure
  • The bearing capacity of end bearing piles is determined by testing the piles in the field
  • The testing is done by applying a load to the pile and measuring the settlements
  • The settlement is the deformation of the pile caused by the applied load
  • The bearing capacity is the load at which the settlement of the pile is equal to the allowable settlement
  • The allowable settlement is the deformation of the pile that is allowed without causing damage to the structure supported by the pile.

Advantages of End Bearing Piles

  • There are many advantages to end bearing piles, including the following:

    1

  • They are very load bearing and can support a lot of weight.

    2

  • They are very stable, making them ideal for supporting structures.

    3

  • They are not susceptible to movements in the ground, making them ideal for areas with sandy or unstable soil.

    4

  • They are easy to install and do not require special equipment.

    5

  • They have a long lifespan and are not susceptible to rot or decay.

Disadvantages of End Bearing Piles

  • 1
  • End bearing piles are more likely to be damaged during installation than friction piles.

    2

  • The weight of the end bearing pile is borne by the end of the pile, which may cause the pile to compress the soil and possibly fail.

    3

  • The tip of the end bearing pile is subject to wear and tear, and may need to be replaced more often than a friction pile.

    4

  • The load carrying capacity of an end bearing pile is less than that of a friction pile.

    5

  • An end bearing pile is more likely to be affected by changes in the moisture content of the soil than a friction pile.

Conclusion

End bearing piles are commonly used to transfer loads from buildings and other structures through the weak uppermost soil strata to stronger soil or rock layers below. End bearing piles are also used in foundation design to resist uplift forces.
