In the paper, the basic design standards (GB50040-96 and ISO10816-2) of various mainstream steam turbine generators at home and abroad were reviewed and their similarities and differences were analyzed in detail. Moreover, the paper also provides the vibration test data on the disturbing points of the foundation and corresponding bearing bracket of three typical 600MW turbine generator units during normal operation so as to search for the relationship between vibration of bearing brackets and vibration of the foundation. The safety coefficient of the chosen foundations using GB50040-96 and ISO10816-2 were also given to compare the severity of each standard. It is hoped to provide designers with accurate grasp of various standards.
