ABSTRACT: Design analyses in rock engineering provide a valuable aid to the engineering assessment of design issues, principally by enabling an insight of complex stability mechanisms and of potential interactions between excavation-support systems. The paper outlines the capabilities of rigorous numerical modeling applied to the case of an underground railway station project in southern Sweden. According to the project requirements, the station will be constructed in a cavern ca. 30 m wide in weak, bedded rock under limited rock cover and beneath significant buildings. Extensive UDEC-BB modeling studies were undertaken in the course of evaluation of different design concepts for this unprecedented scheme.
