摘　　要：光弹性模拟实验表明 ,江西核电厂帽子山厂址区域范围内现代构造应力场分布不均匀 :在大别山北部、泾县及其西北地区、九江 -瑞昌地区、德兴东南地区出现应力集中 ;而在帽子山厂址、厂址附近地区及厂址区域范围内应力强度很低 .由于深断裂的特定组合 ,导致厂址区域范围内主应力方位有规律地变化 ,据此可判断不同稳定性分区的叠加断裂角 .帽子山厂址一主要断裂的叠加断裂角为 80°左右 。A photoelastic investigation for the modern construction stress field in the region around Maozishan Nuclear Plant in Jiangxi Province is made. It shows that the constructional stress distribution is not uniform. It is found that in the vicinity of the plant site exhibits a low stress field and stress concentrations occur in those areas rather far from the site.
