Field records of the boring process should be kept to maintain the integrity of the process. It should also discuss the engineering project and the field and laboratory procedures used. If rock is encountered during the boring process, additional information should be recorded in the boring log, including the thickness and depth of the rock unit; a description of the rock unit; percent recovery and rock quality designation; description of joints, fractures and bedding planes; location of core fracturing; type and size of core barrel and depths where casing is used; descriptions of penetration rate; zones of drilling fluid loss; zones of water gain; and any unusual occurrences, such as change in color of return wash water. stress is much higher than the strength, local to large failures can to blasting and equipment vibration. great because it will have been unexpected; support steel and other top crippling decompression or extensive flooding. to the one contemplated, may provide valuable insight into the stand-up Geology Chamber Publishing, 140, Ankara, p 184, Gocmez D (2005) Geological factors urban effect: Yalova Thermal Placement.
