IN-SITU PENETRATION/ SHEAR

Standard Penetration Test Set
Ref. Standard : IS:2131, IS:9640

EKE 133:

Standard penetration test is a powerful tool for measuring the penetration resistance of the ground and for relating it to the degree of compactness’ of cohesion less soil and consistency of cohesive soil, the results can be used for design of foundations, SPT is widely used for measuring the undisturbed strength of the soil and for assessing its resistance to liquefaction due to ground vibrations caused by earthquakes or other dynamic forces,

The standard penetration resistance is measured as the number of blows “N” required to drive a split spoon sampler to a depth of 300 mm using a 65 kg weight falling freely through a height of 750 mm,

Dynamic Cone Penetration Test Apparatus 
Ref. Standard : IS:4968 (Part-1)

EKE 134:

For determining the resistance of different types of soil strata to dynamic penetration of a 50 mm cone and thereby obtain an indication regarding their relative strength or density or both, the method helps reconnaissance survey of large area in a short time,

In some cases especially if the depth it may be difficult to pull out the cone after the completion of the test, hence the cone without threads should be used in case of deep sounding as it may be left in the ground, For shallow depths, generally upto 15 m, if the conditions permit, the cine with threads may be used.
