3D ground-use optimisation for sustainable urban development planning: A case-study from Earls Court, London, UK
Introduction: research context and objectives Cities provide opportunities for economic growth, cultural and social development and scientific and technological innovation. Yet they have often developed without coordination and integration of … Read More
3D reflection seismic imaging at the 2.5 km deep COSC-1 scientific borehole, central Scandinavian Caledonides
Introduction The Scandinavian Caledonides represent one of the best preserved inactive orogens in the world in which to study thrust tectonics (Asklund, 1960, Gee, 1978, Hossack and Cooper, 1986, Törnebohm, … Read More
Tunneling and deep excavations in spatially variable soil and rock masses
Introduction With the growing demands for social and economic development and limitations on land or environments, additional tunnels are often necessary to establish links between different areas (Xiao et al., … Read More
Tunnel behaviour and support associated with the weak rock masses of flysch
Introduction Since the last decades of the 20th century, there has been a rapid development in various stages of geotechnical design, analysis and computational methods. Yet, regardless of the capabilities … Read More
Geostructural stability assessment of cave using rock surface discontinuity extracted from terrestrial laser scanning point cloud
Introduction Rocks naturally begin as lateral bedding of sedimentary layers (Oberender and Plan, 2015). However, under the action of tectonic stress, rock folds and fractures, resulting in discontinuous rock mass … Read More
Applying the Seismic Refraction Tomography for Site Characterization
Introduction Seismic refraction was the first major geophysical method to be applied in the search for oil bearing structures but its application in oil exploration is reduce over years due … Read More
3D representation of geological observations in underground mine workings of the Upper Silesian Coal Basin
Introduction Mapping underground mine workings means following their definition and presenting rock complexity revealed by the mine workings in a graphical form. Methods of mapping individual mine workings differ, because … Read More
3D Geological Modeling and Its Application under Complex Geological Conditions
Introduction The 3D visualization can give people an intuitive feel. The virtual reality technology can create a virtual environment. The common influence of visual sense, auditory sense and tactile sense … Read More
What is the Wilson cycle?
