Standard Penetration Test (SPT) Procedure Aim To perform standard penetration to obtain the penetration resistance (N-value) along the depth at a given site. Equipment & Apparatus Tripod (to give a clear height of about 4 m; one of the legs of the tripod should have ladder to facilitate a person to reach tripod head.)
Dec 24, 1981· IS : 2131 - 1981 2. EQUIPMENT 2.1 Drilling Equipment 2.1.1 The equipment used shall provide a clean borehole, 100 to 150 mm in diameter, for insertion of the sampler to ensure that the penetration test is performed on undisturbed soil and shall permit driving of the split
The purpose of the Standard Penetration Test is to identify the soil stratification and engineering properties of soil layers. During the SPT, it was possible to take disturbed and undisturbed samples (using split barrel-sampler) which were used for further laboratory tests.
