The point-load test in geotechnical practice

Abstract The point-load test is evaluated for practical applications in engineering geology. The three variations of the test, i.e., diametral, axial and irregular lump are assessed and it is found that the diametral point-load test is most convenient and reliable in use. The relationships between the uniaxial compressive strength and the point-load index separately for NX, BX and EX core diameters are established and a simple size correlation graph is compiled. Practical applications of the point-load test in geotechnical practice are discussed.
