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
Ground-penetrating radar studies of permafrost, periglacial, and near-surface geology at McMurdo Station, Antarctica
Introduction McMurdo Station, located on Hut Point Peninsula of Ross Island, was first used as a shoreline base in 1902 to explore inland Antarctica (Fig. 1). The United States more … Read More
Numerical evaluation of new Austrian tunneling method excavation sequences: A case study
Introduction Tunnels provide a feasible alternative to cross through the physical barriers or water body. With the rapid development of the world, the utilization of underground space plays an important … Read More
Effect of discrete fibre reinforcement on soil tensile strength
Introduction Compared with compressive or shear strength, tensile strength of soil is basically assumed to be zero, or insignificant in geotechnical engineering practice because of its relatively low value. In … Read More
Stabilizing soft clay using geo-foam beads and cement bypass dust
Introduction Expanded polystyrene (EPS) geo-foam blocks are used as a lightweight fill in a wide range of geotechnical applications. The primary function of geo-foam is to provide a lightweight fill … Read More
Underground ground control monitoring and interpretation, and numerical modeling, and shield capacity design
Introduction–non-uniform in situ stresses and high horizontal stresses in mine environments Coal mining is a type of manufacturing enterprise. But unlike manufacturing where it builds a covered structure and begins … Read More
Geophysical investigation of a freshwater lens on the island of Langeoog, Germany – Insights from combined HEM, TEM and MRS data
Introduction The W-E trending barrier island of Langeoog is located at the German North Sea coast, along the northern rim of the intertidal Wadden Sea (Fig. 1a). The water supply … Read More
Large borehole with multi-lateral branches: A novel solution for exploitation of clayey silt hydrate
Introduction Natural gas hydrate, as a kind of novel, efficient and environment-friendly substitute energy, is widely distributed in continental permafrost zones and seafloors along continental margins (Kvenvolden KA, 1995; Boswell … Read More
Geoelectrical monitoring of simulated subsurface leakage to support high-hazard nuclear decommissioning at the Sellafield Site, UK
Introduction Whilst modern geophysical methodology is increasingly applied at nuclear legacy sites worldwide, the full potential of near-surface geophysics has yet to be fully recognized by the nuclear industry and … Read More
