Define constant-rate-of-penetration test.

Expert Solution
Step

Constant rate-of-penetration test-

It is defined as the method of application of loading in which the test piled is jacked into the soil and the load is adjusted in such a way that it gives a constant rate of downward movement.

Characteristics of Constant rate-of-penetration test-

  • It helps in determining the safe load of a pile.
  • In this Maximum skin, friction mobilizes at small penetration of 5 to 10 mm.
  • In this maximum base, resistance mobilizes at a relatively large penetration.
  • It helps in verifying the structural soundness of the pile.
  • It determines the load-settlement curve.

 

 

 

Advantages of Constant rate-of-penetration test-

  • In Constant rate-of-penetration test curve attain progressive failure.
  • It is used for finding combined friction resistance.

 

Disadvantages of Constant rate-of-penetration test-

  • It is a time taking method.
  • In this design, resistance is calculated on an allowable basis which is not preferred nowadays.
