Permafrost is defined as soil which remains frozen for at least two consecutive years. In the Swiss Alps, it is a widespread phenomenon with a great impact on the landscape particularly regarding natural hazards. The occurrence of permafrost is not only influenced by meteorological ...

Deformation prediction is an important part of the structure stability analysis. However, the deformation of bank protection structure which is affected by many factors, such as structural stiffness, earth pressure and hydrostatic pressure. It contains a complex mechanical process, which ... Per saperne di più
Accurate estimation of rock permeability and porosity play a crucial role in the evaluation of oil and gas reservoirs. This evaluation is, however, challenging in tight formations such as shale due to the slow transition of fluid in such formations with extremely-low permeability. To ... Per saperne di più
An estimation method, known as Thermal Response Test, of the soil thermal properties necessary to the design of a borehole geothermal energy storage system is discussed in relation to its application to the ground having non–homogeneous composition. The governing equations of the ... Per saperne di più
To investigate the thermal-mechanical behavior of oceanic transform faults, we calculate 3-D steady-state incompressible mantle flow and heat transport using COMSOL Multiphysics. Our model incorporates a nonlinear viscous rheology with a visco-plastic approximation to simulate ... Per saperne di più
To assess the safety deep geological repositories for nuclear waste, it is important to have a clear understanding of groundwater flow at the interface between the storage vault and the fractured rock. Traditional approaches for modelling groundwater often consider both the geological ... Per saperne di più
An energy pile harvests geothermal energy to heat and cool a building by integrating ground heat exchanger (GHX) pipes into the building’s deep foundation, and extracts heat from the ground in the winter to heat buildings and injects heat into the ground during the summer. In areas with ... Per saperne di più
为研究不同加热方式下煤岩内部裂隙在热力耦合作用下的变形特征，建立了微波和常规加热两种数值模型，考查了不同温度场分布特征下裂隙周边应力应变场的变化过程。研究结果表明：微波加热，温度场分布具有内高外低的特征，此时裂隙周边分布的应力多为压应力，且数值较大，裂隙边界位移表现为向内收缩；常规加热，温度场分布具有外高内低的特性，此时裂隙周边分布应力多为拉应力，但量值较低，裂隙边界位移表现为向外扩张；热源越靠近裂隙压应力越明显，反之拉应力明显。 Per saperne di più
Mass transport modelling through porous media is typically characterized by complex physics and geometry. In the particular case of radionuclide transport, modelling for radioactive waste repositories, an additional level of complexity, and thus uncertainty, originates from the long time ...

Electrical resistivity surveys have been used for many decades in hydro geological, mining and geotechnical investigations. Various types of electrode combinations have been tested. But different array gives different type of response over same sub-surface feature. Response of different ... Per saperne di più
