| 摘 要： | 关于核电站场地断层活动性识别标准,作者提出了6点建议:1. 晚更新世、特别是全新世地层被扰动或错断;2. 断层泥年龄小于10万年;3. 沿断裂带存在明显的线性构造;4. 有破坏性地震(Ms≥5. 0) 沿断层发生;5. 现代微小地震沿断裂带形成“地震线”;6. 在断裂带上发现可靠的古地震遗迹。此外,为了使断层活动性评定做到定量化,作者还提出了断层活动度概念。

| Abstract: | In this paper six recognizable criteria are proposed for evaluating the fault ac-tivity in the nuclear power plant site.They are:(1) the late Pleistoccne-Holocenestrata disturbed or offset by the fault,(2) the ages of the gouge of less than 10~5years,(3) the remarkable lineament existed along the fault zone,(4) the destructiveearthquake(Ms>5. 0) occurred in the fault zone,(5) a lot of the microearthquakesdistributed along the fault zone,which usually are called earthquake line,and(6)the relic of paleoearthquake existed in the fault zone.Besides,the author proposes the conception of the activity degree of fault,which is applied to a quantitative criteria for evaluating fault activity. |
