AN EXPERIMENTAL STUDY ON EFFECT OF CONE DIAMETERS IN PENETRATION TEST ON SANDY SOIL

Cone Penetration Test (CPT) is an exploration tool used in site investigation and soil exploration. It has a long history in geotechnical engineering. From the basic tool of the Dutch to the advanced integrated modulus type, CPT had developed so much over the years. A considerable amount of experience and knowledge have been gained on the value of this method in the understanding and evaluation of the local soils behaviour. The sand collected from the Construction site of has been tested using CPT with different void ratio and different Diameters of 25mm, 20mm, 15mm. This study extracts about the effect of cone diameter in cone penetration test on sand, effect of moisture content on diameter, effect of Void ratio on cone diameter it can be concluded that the greater the Diameter, the lesser will be the Depth of penetration and Higher Penetration resistance
