Soil and rock description in engineering practice
1 online resource (xvi, 288 pages) : illustrations (some color)
Annotation In ground investigation, the description of soils and rocks inengineering practice forms a major input to the field log. The log records the materials and strata seen in any sample, core or exposure and is a basic element of the factual information that underpins the entire understanding and interpretation of the ground conditions on site. The field log is also all that remains after the investigation is over and so has a life well beyond that of the investigation report. Practical guidance is provided for those in the field carrying out engineering geological logging of soil and rock samples and exposures. Information on the current systematic and codified approach and its use are laid out in detail to ensure the defined descriptors are used in a consistent format, rendering mistakes less likely and the necessary communication from field to design more successful. The procedures, techniques and tips within this book are not only for young practitioners learning their craft, but are also relevant for theirseniors and mentors, including responsible experts who sign off the logs and report on behalf of their company. Althoughthey may have been involved in logging for many years they need to be aware of current practices in order to avoid costlymistakes. Soil and Rock Description in Engineering Practice enables the practitioner to record and present features of theground from the exposure in such a way as to convey a field presence to subsequent users of the data. This is important as the samples deteriorate quickly and are not usually inspected by any party other than the logger. Field logs therefore provide the only record of the ground that is available to the designer and contractor later in the construction process.
