Grouting techniques for the unfavorable geological conditions of Xiang’an subsea tunnel in China
Introduction The geological conditions of subsea tunnels are rather difficult to accurately explore because of the close proximity of an infinite amount of seawater. Therefore subsea tunnels are greatly affected … Read More
Variscan cycling of gold into a global coal reservoir
Introduction In just a few years, awareness and interest in the resources of trace elements in coal has greatly increased (Tolhurst, 2015, Yao et al., 2015, Dai and Finkelman, 2018, … Read More
Geophysical methods for mapping Quaternary sediment thickness: Application to the Saint-Lary basin (French Pyrenees)
Introduction Mountainous glacial valleys commonly exhibit characteristic parabolic or “U”-shape transverse sections which are extensively studied and discussed in the literature (Augustinus, 1995, Harbor, 1990, Harbor et al., 1988, Hirano … Read More
Rock mechanical modelling of the Bentonite Rock Interaction Experiment, Äspö Hard Rock Laboratory, Sweden
Introduction An important task for a society that aims at sustainability is to be able to conceptualise, characterise and model different geological systems. The ability to transmit and store fluids … Read More
Mapping erosion and deposition in an agricultural landscape: Optimization of UAV image acquisition schemes for SfM-MVS
Introduction Structure-from-motion (SfM) is a photogrammetric technique used to generate a 3D pointcloud from a collection of overlapping 2D images (Carrivick et al., 2016). The SfM process starts with feature … Read More
Full-face excavation of large tunnels in difficult conditions
Introduction No established method was available at the beginning of the 20th century for the design and excavation of tunnels in difficult conditions. However, with the need of new transportation … Read More
Rock Grouting In Copenhagen Limestone – The Cityringen Experience
Introduction The Cityringen Metro is expected to be running in 2019 and will consist of two single tracks in twin tunnels, each approximately 16.5 km in length. A total of … Read More
The weathering of granitic rocks in a hyper-arid and hypothermal environment: A case study from the Sør-Rondane Mountains, East Antarctica
Introduction The weathering process in Antarctica is key to our understanding of the geomorphological processes that take place in hyper-arid and hypothermal environments on Earth. Although rock disintegration and soil … Read More
Design of rock support system under rockburst condition
Introduction As the depth of mining and civil underground construction increases, stress-induced rock fracturing is inevitable and when stored energy is suddenly released, rocks fail violently, leading to seismic events … Read More
