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 ,在现代构造应力场中无活动的可能性
The results of photoelastic simulation show that the distribution of stress field of modern tectonic stress in the area of Hatzishan site in Jiangxi NPP is not uniform: stress concentration occurs in the north of Dabieshan, Jingxian and its northwestern regions, Jiujiang-Ruichang and southeast Dexing; Due to the special combination of deep faults, the orientation of principal stress in the area of the site changes regularly, and the superimposed fracture angle of different stability zones can be judged. The superimposed fracture angle of a major fault at Hatishan site is about 80 °, with no possibility of activity in modern tectonic stress field
