A glacial terrain map of britain for engineering purposes
Abstract The engineering importance of superficial soils in Britain cannot be overemphasized. They range in age from Quaternary to Recent and vary from overconsolidated bouldery silty clays: tills, through normally consolidated clays, laminated clays, silts, sands and gravels, to peats and organic soils. Associated with the superficial soils are superficial structures involving both soil and rock and resulting from glacial and periglacial activity. For engineering construction, these structures may give rise to problematic grround conditions. For ground conditions resulting from glacial and periglacial conditions four generalised terrain models are presented as annotated block diagrams. These diagrams represent subglacial terrain, supraglacial terrain, glaciated valley terrain and periglacial terrain. The four terrain models are supported by maps illustrating the distribution of superficial engineering soils, the distribution of predominant glacial terrain types and selected periglacial features. The distinctive terrain types each have both characteristic topography and subsurface conditions. If the landforms and hence the terrain types can be identified, then the geometry and character of the subsurface—both soils and bedrock conditions—can be generally predicted. By recognising these terrain types the character of subsurface ground conditions can be generalised for large areas. The value of this approach to ground engineering lies in its use as an engineering geological mapping tool and as a rapid guide to likely subsurface conditions.
