Conference Paper
It is well known that vegetation influences slope stability in following ways: (1) By mechanical reinforcement from the plant roots; (2) by increasing in soil suction or reduction of pore water pressure; (3) by surcharge from the weight of trees; and (4) by"wind throwing." The main beneficial effect includes root reinforcement. Roots increase the s...

Results of a systematic testing program showed that the cyclic behavior of silt–clay mixtures is greatly influenced by the dominant clay minerals in the mixture. In particular, it was demonstrated that given the same amount of clay/clay mineral and/or same value of plasticity index, the montmorillonitic soils have the highest cyclic strength, follo...

The run-off rain water of infrastructure surfaces is nowadays seeped extensively. A specific pretreatment of the surface water, containing de-icing agent in winter, does normally not occur. The de-icing agent (potassium formate) is diminished during the absorbing-processes by the micro-organisms available in the natural soil. For the scientific res...

The re-use of old foundations for new construction work is set to play an increasingly important role in urban areas. Previous attempts at this have always been impeded by uncertainties about flatness and doubts as to the condition of the foundations. This is where non-destructive testing can help. In recent years methods have been developed and re...

Struts are the most sensitive elements of deep excavations. Their failure might cause the collapse of the whole excavation damaging adjacent structures. Thus high demands have to be made on the reliability of the calculation model used to predict the forces within a spatial bracing system. Different from line-wise excavations, the design of spatial...
