摘　　要：岩体地基由于强度高,地基承载力大,对一般建筑物可视为均匀地基。但核电工程对地基的强度、均匀性等要求都非常高,必须评价其均匀性。对核电工程等重大工程的岩石地基均匀性评价,目前还没有非常规范的方法。本文拟从地形地貌、地质构造、波速特征、地基承载力以及地基沉降均匀性等方面加以评价,并结合用Hoek-Brown准则预测岩体强度进行地基强度均匀性评价。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 homogeneousness of topography and geomorphology,geological structure,wave characteristic,subgrade bearing capacity,and foundation settlement,combined with predicting the strength of rock foundation through Hoek-Brown Rule.
