TS 6108

TS 6108 is a terminology standard for terms used in engineering geology and their definitions. Standards of this kind help prevent the same technical concept from being used differently across organisations or disciplines, and they provide a common language for engineering communication about ground conditions, rock masses, landforms, and geological processes.

What engineering geology terminology supports

Engineering geology examines how geological materials and site conditions affect engineered works. In projects such as roads, dams, tunnels, foundations, and slopes, rock properties, weathering, discontinuities, groundwater, and geologic structure can directly influence design and construction decisions. By defining the terms used in this field, the standard supports consistent understanding in reports, design documentation, field descriptions, and technical discussions.

The kind of content covered

• Names and definitions used in engineering geology
• Technical vocabulary related to geological materials, structures, and processes
• A shared terminology base for technical communication and documentation

In general technical context, engineering geology is closely linked to rock mass behaviour, the distinction between soil and rock, the role of geological discontinuities, erosion, landslides, and the influence of water on geotechnical performance. Clear and consistent terminology matters not only for academic precision but also for site investigations, design input, and risk assessment. TS 6108 serves as a reference that standardises this terminology framework.
