Abstract: Rock foundation can be treated as homogeneous for general buildings for its high strength and high subgrade bearing capacity. But nuclear power engineering has strict requirement for the strength and homogeneousness of foundation,so foundation homogeneousness must be evaluated. There are no normative methods for the evaluation of rock foundation of major engineerings such as nuclear power engineerings. This paper evaluates the homogeneousness of rock foundation in the aspects of the homogeneousn...
