Soil is a granular material. During mechanical loading its deformation behaviour is characterized by some unique particularities. The research at the institute deals e.g. with the analyses of soil behaviour under laboratory conditions but also with its numerical description by developing mathematical models.

What are the special features of hot lime mortar? The working group of Applied Geology analyses the classical operation method with hot lime mortar in order to preserve and share the knowledge. Furthermore, empirically observed advantages of this operation method are proven by technical parameters.

If numerous ground investigations have to be carried out, Cone Penetration Tests (CPTs) are suitable because of their simple realization. However, the evaluation and interpretation of the measurement results still needs some research.

The soil under a planned construction needs to be improved when the applied loads cannot be borne. Measures for soil improvement are e.g. deep vibro compaction or deep vibro replacement techniques. But what happens in the ground during the installation process?

… and their stability are concerns which in mountainous regions humans face since centuries. The interpretation of slope displacements and the possible early detection of landslides plays an important role in research.

Open-cast mines with depth of several 100m present some challenges for geotechnical engineers. Not only the slope stability of the cut slopes but also the skilful dumping of overburden and the groundwater-lowering in a large area are important issues.

Loose packed, coarse grained soils which are fully water-saturated tend to liquefy during a sudden loading. But what happens during liquefaction and why does solid ground can suddenly turn into liquid?

The leaning tower of Pisa is the best example that also for historical buildings geotechnics still plays an important role. Furthermore, the preservation of historical monuments and the foundation restoration after flood damages belong to the field of geotechnics.

Round or angular, smooth or rough – soil grains can have various sizes, shapes and surface textures. All these features can influence the mechanical characteristics of a soil.

How does soil behave under dynamic loading as an earthquake? How do slopes have to be dimensioned to resist an earthquake? An is it possible to improve the construction ground to withstand an earthquake?
