Cone Penetrometer Test
Abstract This chapter covers one of the most popular insitu tests, the cone penetrometer test (CPT). A brief description of different types of tests has been provided. The piezocone test, an advanced CPT, is described including the test procedure and the parameters obtained in the field. Pore pressure transducer placement locations and the corrections to measured pore pressures are presented. A detailed discussion of soil classification using cone test results is provided. Correlations for design parameters related to sands and clays are discussed separately. For sands, correlations include relative density, friction angle, modulus and small strain modulus. For clays, correlations include the undrained shear strength, over consolidation ratio, constrained modulus, small strain shear modulus, compressibility, friction angle, unit weight and permeability. As the CPT test competes with SPT test for popularity, correlations between the two tests are also discussed. Correlations to use CPT derived parameters directly to calculate the ultimate bearing capacity of shallw and deep foundations are presented. The chapter concludes with a section on liquefaction assessment using CPT as well as SPT results.
