Geotechnical Core Logging

Geotechnial Core Logging is the process of recording rock descriptions on boring logs, where primary means of communicating rock properties are used in the design and construction of underground works including foundations in and on rock, rock slope and tunnel support, and excavations in rock. Technical Data used in the field explained in drilling courses in Islamabad. The quality of rock descriptions can have far-reaching implications for the success of a project. An appropriate level of detail (as determined by the project-specific end use objective) must be collected and conveyed.

Important considerations for geotechnical core logging include: . Rock descriptions developed for each rock material unit, defined as discrete mass exhibiting a different set of geologic and engineering properties than adjacent materials. Material unit-based rock core logging minimizes the risk of overlooking design-critical rock mass conditions. . Material unit descriptions should be constructed using a standard descriptive code consisting of well-defined terminology arranged in a consistent format. . Standardization of the rock core logging descriptive code (at least for individual projects) will result in more useful rock descriptions to facilitate geo-engineering interpretation, spatial correlation of material units, and engineering analysis for developing design recommendations and construction considerations. Some more details of drilling courses in Islamabad are as under.

One of the most important things to do at the drill rig is photograph the undisturbed core in the splits. These photos may be used later to confirm televiewer images and will be an invaluable resource on the rock mass and for review of the design work.

Proper core photos require that the core be cleaned prior to photographing. When core is covered in drilling mud, structural information can be obscured making it difficult to determine lithologies. Take the time to properly clean the core. The core should be wet if possible as some structural features do not show up on dry core so make sure to wet it down with a spray bottle or paint brush.
