Research

LOC3G project seeks to advance the knowledge of multiscale and multiphysics localization phenomena in porous geological media, with the aim of creating new predictive models for geophysics, geohazards, and geoengineering. The consortium combines a diverse array of expertise, including geological surveys, constitutive modeling and numerical simulations, laboratory tests, and real-world applications such as CO2 storage and geo-resource/energy exploitation. The project will incorporate innovative research techniques and utilize advanced constitutive models and next-generation numerical approaches to investigate the localization of deformation in geological media. The ultimate goal is to provide cutting-edge knowledge and interdisciplinary training to improve the capacity for research and technology globally, and to provide practitioners with the tools they require to tackle relevant problems in their fields. Additionally, LOC3G is expected to have a significant impact on addressing EU energy crisis caused by geopolitical issues.

With the rise of digitalization in the construction industry, this area is also becoming increasingly important in specialist civil engineering. In addition to areas such as building information modeling, the main focus here is on mapping the subsoil and the numerical analysis of geotechnical structures. With the former, it is possible to provide a more comprehensive representation of the subsoil and subsequently reduce the subsoil risk and also create optimization possibilities. The second method also offers the potential to generate improvements and optimizations while still ensuring stable and robust structures. The interaction of both methods offers the opportunity to utilize overlapping areas and synergy effects and thus contribute to the conservation of resources. Compared to other engineering disciplines, there is a considerable amount of catching up to do in the area of ground improvement and the foundation of structures in interaction with the structural components, as far as such interacting processes are concerned. The concept of the GaSIm research project conceived by the VÖBU - as an interest group in special civil engineering - offers the opportunity to carry out such considerations from a scientific point of view and thus to create an essential building block for the development of the second generation of the Eurocode.

A device for charging concrete in tremie pipe Bored piles and diaphragm walls are important foundation elements with very wide applications. Bleeding in fresh concrete leaves channels in the concrete and leads to loss of quality. The cause lies in the contractor process with contractor pipe. We will carry out modelling tests to better understand the mechanisms. We will also make an umbrella-like device and test it in a plexiglass tube. The experiments will be carried out on small and large scales. The falling speed of the concrete in the contractor tube is to be measured. The segregation of the concrete should be observed.
