The book "Cone-Penetration Testing in Geotechnical Practice" by T. Lunne, P. K. Robertson, and J. J. M. Powell is presented within the framework of the Gersevanov lectures. Published by SPON Press, Taylor and Francis Group, it provides an extensive overview of cone-penetration testing (CPT), a method for in-situ testing of soil beds by cone penetration. This method is effective and universal for acquiring data on soil stratification and physico-mechanical properties at various depths under different conditions, including those on the continental shelf. The book addresses various problems, including testing equipment and procedures, data interpretation with practical examples, the relationship between CPT data and laboratory tests, and the use of test results for design and construction. It is useful for engineers, surveyors, students, instructors, and lecturers. The book is published in English but is also beneficial for the Russian-speaking audience. It contains reference information for international cooperation, including international notations, unit conversions, and definitions. It includes many diagrams, tables, illustrations, and practical examples with universally accepted notations. The book was first published in 1997 and has been reprinted in several countries. It is divided into 12 chapters, covering topics from introduction to practical examples and prospects for development. The book includes a list of cited literature with approximately 600 authors, an alphabetized directory, and appendices on international standard procedures, Swedish standards, and a calibration chamber for sandy soils.The book "Cone-Penetration Testing in Geotechnical Practice" by T.
