Experimental Rock Mechanics
Fracture and flow of rocks under stress and their geophysical and seismological implications raise fundamental questions in rock mechanics, particularly in the areas of tectonophysics and seismology. This text exclusively addresses the deformation and fracture of rock specimens under general triaxial compression, in which all three principal stresses are different; which significantly affects the ultimate strength of rocks. It moreover deals with deformation and failure following intermediate principal stress in graphic and numerical form. The effect of the intrinsic features of rock masses of inhomogeneous or anisotropic structure are taken into account, as are acoustic emission phenomena in rocks under various stress states. Friction in rocks, measured by a newly-designed shear-testing machine, is discussed in relation to earthquake phenomena.
Testing and Performance of Geosynthetics in Subsurface Drainage
L. David Suits, James B. Goddard, John S. Baldwin ... Language: English - ISBN-10: 0803128606 - ISBN-13: 978-0803128606
This unique volume provides new information on the testing, application, and installation of geosynthetics used in drainage applications in roadway and landfills. 9 papers divided into 3 sections cover the following: Field Performance Studies--examines the performance of 3 different geocomposite materials. They include a geonet with a geotextile, a geopipe wrapped with a geotextile, and geocomposite capillary drain barrier. Pavement Design And Drainage--describes the use of geocomposite drainage layers in the base and subgrade of a roadway system, the use of geosynthetics in pavement drainage in cold climates, the development of performance-based specifications for highway edge drains, and some key installation issues on the use of geocomposite edge drain systems. Testing--explores 4 different laboratory testing programs to evaluate different aspects of geosynthetic drainage systems. They include the laboratory testing of a toe drain with a geotextile sock, two reports on a modified gradient ratio test system with micro pore pressure transducers inserted into the system, and a discussion on the influence of test conditions on transmissivity test results for geotextile drains. STP 1390 is a valuable resource for engineers in the following fields: geotechnical, geosynthetic, transportation, hydraulics, pavement, sanitary, and environmental. Also for civil engineering consultants, project inspectors, and testing agencies.
Nondestructive Testing of Deep Foundations
Bernard Hertlein, Allen Davis ... 290 pages - Publisher: Wiley; 1st edition (August, 2006) ... Language: English - ISBN-10: 0470848502 - ISBN-13: 978-0470848500 ...
Nondestructive Testing involves the use of methods such as wave propagation, electromagnetism, electrical conductivity, and thermal conductivity to test structural integrity and thereby allow nondestructive assessment of structures and the possibility of structural failures before they occur. Nondestructive Testing of Deep Foundations covers different techniques designed to provide information about the integrity and quality of the material that makes up a deep foundation. Nondestructive Testing methods are used at all stages of a structure's life - from new construction quality control to residual lifetime prediction, and even during the monitoring of demolition. In addition, Nondestructive Testing is being increasingly specified in deep foundation projects, though often without a good understanding of its limitations and with the result that methods are often misused. In order to be able to specify an appropriate method, or to recognize an inappropriate specification, it is necessary for the engineer, specifier and/or contractor to understand the capabilities and limitations of each of the methods currently in use. Nondestructive Testing of Deep Foundations: * Describes the most commonly used deep foundation construction techniques, including typical use of material* Provides a brief history of the development of commercially available nondestructive methods* Summarises each method's capabilities and limitations* Acts as a one stop reference drawing together resources only previously available in conference proceedings and journal papers This manual will prove to be a welcome addition to the bookshelf of all practitioners in civil/structural and geotechnical engineering and architecture. It will also provide a valuable insight into this highly technical field for university researchers, lecturers and postgraduate students in civil/structural and geotechnical engineering.

A Rapid Load Test (RLT), developed to determine the initial stiffness and bearing capacity, is an economical and practical alternative to a Static Load Test (SLT). The broad application of RLT, however, was hampered by uncertainty about the interpretation of the test results. This book offers clear guidance on the available analysis techniques and their reliability.The guidelines were related to an international standard that is drawn up by CEN and can be used in two ways: +Straightforward interpretation of test results, chapters 1-3 +Interpretation with additional background information about the possibilities and limitations, chapters 4-8.
The guidelines were drawn up by the Dutch CUR-committee on rapid load testing on piles: Chapters 1 and 2 deal with the practical execution of the test and the presentation of the results. Chapter 3 gives a general overview of existing interpretation methods and refers to step-by-step descriptions of the two advised interpretation methods. The aspects that are important for the interpretation are discussed in chapter 4, also showing that the inertia of the pile should be taken into account. In clay soil the rate effect (the dependency of strength and stiffness on loading rate) is also of importance, whereas in sand and silt the generation of pore water pressures during an RLT plays a role. The velocity of the RLT is such that the reaction of sand and silt might be considered as partially drained. These guidelines indicate how these effects can be compensated to obtain the static resistance in the final results. Chapter 5 presents two interpretation methods (a method for piles in sand, gravel, silt and piles on rock and a method for piles in clay). For practical use, the methods are described in a step-by-step scheme in an appendix.
A Short Course in Geotechnical Site Investigation
368 pages - Publisher: Thomas Telford Publishing; (January, 2002) ... Language: English - ISBN-10: 0727729489 - ISBN-13: 978-0727729484 ...
A short course in geotechnical site investigation is the third volume in the popular and authoritative 'Short course' series. This book focuses on the fundamental principles of geotechnical site investigation - in particular the planning of the investigation. This indispensable book is illustrated throughout with 23 case studies, seven of which are detailed examples of best practice. Some aspects of soil mechanics are explained using 'hand written' Short Course Notes.
