The influence of the energy (heat) stored in the earth as a major factor in environmental soil processes is recognized by the soil science community. The heat (energy) supplied by the earth is known to fluctuate with depth below ground surface and time of year, obviously as a function ... 詳細を見る

The objective of this study is to acquire a full characterization of a hyper-elastic material. The process is realized by performing a Dynamic Mechanical Analysis (DMA) with a viscoelastic material, which is extended by image processing algorithms in order to measure the changing ... 詳細を見る

In this work a modified anisotropic creep model with structure for soft soils was implemented by using the Physics Builder. The model is validated against boundary value laboratory test such as undrained tri-axial tests and CRS (constant rate of strain) tests. The implemented user ... 詳細を見る

This work investigates the possibility of thermal activation of future tunnels to heat and/or cool the surface buildings or infrastructure such as subways stations. The principle is to insert pipes in the tunnel lining segments, which are connected to a geothermal pump. A heat transfer ... 詳細を見る

Gas generation and transport through porous media is a process common to many field applications such as radioactive waste and underground gas storage. In these operations, the gas phase evolution depends on the thermodynamic conditions at depth, the properties of the fluids (density, ... 詳細を見る

Hydrophobic meshes are a new, promising technique for the recovery of spilled oil in the ocean. They allow to recover and store oil, while filtering it from the surrounding water. They are clean, efficient and can be used in continuously. These meshes have one drawback, however: if they ... 詳細を見る

A model is presented for heat rejection in the subsurface. Geometries of different dimension are coupled by linear and general extrusions. In that way it is possible to deal with multi-scale physical set-up. An example shows the high influence of groundwater flow. 詳細を見る

In this study, based on a bank protection structure engineering at Yangtze River, a 2D water-soil coupling model is established, in which the influence of water level fluctuation on groundwater seepage and soil shear strength is considered. According to the water level measured data of ... 詳細を見る

Based on the heat transfer and seepage theory in porous media, a 2D cross section of a horizontal AGF project is selected and a numerical model is set up, which is based on full coupling of temperature and flow fields by combining physical interfaces of Darcy's Law and Heat Transfer in ... 詳細を見る

The Geoenvironmental Engineering Group of the University of Castilla-La Mancha is developing a computational tool, M4B, for describing the influence of environmental loads on the deformation behavior of soils and its interaction with building foundations. This tool comprises a set of ... 詳細を見る
