摘要

In this paper continuous and discontinuous analyses are performed for calculating stresses and displacements of Gjovik Olympic Cavern which was built for the 1994 Winter Olympic Games in Norway. Phase~2, a two-dimensional non-linear finite element program, and the Discontinuous Deformation Analysis (DDA) are used as representative tools for respectively continuous and discontinuous programs. For the continuous analyses both linearly elastic and non-linear analyses are carried out. A construction sequence of five stages is also simulated. The results from the Phase~2 calculations are compared with the results from the DDA calculations. The reason why Gjovik Olympic Cavern was used as a case study is the large amount of available input data through a comprehensive stress and deformation monitoring program during the excavation. The analysis results show good agreement with the reality and also w th analyses carried out in UDEC-BB and the finite element program COSHWAN, by the Norwegian Geotechnical Institute and S1NTEF respectively.
