Existing underground structures in the vicinity of new constructions
Abstract: Large construction projects in inner cities have an influence not only on neighbouring buildings at the surface, but also on existing underground structures, e.g. tunnels and stations of urban metros systems. The influence on existing underground structures can be caused by the construction of new buildings or by the deconstruction of existing structures. The stability and the serviceability of...

Independent peer review processes regarding stability and serviceability during planning, design and construction of...
Abstract: The increasing size and population density of metropolitan areas and the along going traffic demands lead to the construction of large infrastructure projects. The construction of new underground structures has an influence on existing superstructures and the deconstruction of existing buildings has an influence on existing underground structures. To guarantee the stability and the...

Stability, traffic safety and durability of underground structures during service time guaranteed by engineering...
Abstract: To guarantee the stability, traffic safety and durability of underground structures a continuously inspection and supervision is necessary. Based on existing general standards and regulations for civil engineering structures a new concept for engineering inspection and supervision of tunnels and underground structures of urban metro systems has been developed by the Institute and Laboratory of...

Tunnel constructions in swelling rock
Abstract: The swelling process in the cause of the reaction of anhydrite with water has a huge influence on the vicinity and surrounding structures. This special material behaviour caused numerous problems at tunnel construction projects. Large deformations accured and damaged the construction or the sealing system. The material behaviour of anhydrite is strongly time dependent and may last over years....
