摘要:
统计分析了1980年以来新丰江水库水位变化与库区不同区域、库区3级以上地震、小震频次变化的对应关系。库区地震活动统计结果显示:震级和水位有一定程度负相关性。2012年以来鱼坑、锡场等区域易发生在相对高水位时间段,而大坝附近的地震相对容易发生在低水位时间段。库区3.5级以上地震更容易发生在水位卸载时间段内。库区水位高于103m和小震频度增加的发生存在一定的关联性。
Abstract:
This paper statistically analyzes the corresponding relationship between the water level change of Xinfengjiang Reservoir and the frequency change of earthquakes with M≥3 and small earthquakes in different parts of the reservoir area and reservoir area since 1980. The statistical results of seismic activity in the reservoir area show that there is a certain degree of negative correlation between earthquake magnitude and water level. Since 2012,earthquakes in Yukeng,Xichang and other areas are prone to occur in relatively high water level periods,while earthquakes near the dam are relatively prone to occur in low water level periods. Earthquakes with M≥3.5 in the reservoir area are more likely to occur during the unloading period of water level. There is a certain correlation between the water level in the reservoir area higher than 103 m and the increase in the frequency of small earthquake.
