CONE PENETRATION TESTING: METHODS AND INTERPRETATION

This book reviews the use and interpretation of the cone penetration test (cpt), and explains how the test results provide information relevant to geotechnical engineering. Test principles, equipment and procedures are described with advice on good practice. The application of the technique in providing a rapid, continuous profile of the soil together with data on soil strength and deformability is examined in relation to the different types of cone and test procedure. The book brings together published correlations linking cpt results with soil type and engineering parameters for cohesionless and cohesive soils. The reliability of these empirical correlations is discussed and the importance of site specific or local correlations is emphasised. The use of cpt results for foundation design (spread footings and piles) is explained. The combination of pore pressure measurements with the cpt, using piezometers, which is at an early stage of development, is introduced with guidance on the assessment of engineering parameters from this technique.
