水库水位变化与地震活动关系研究
|
摘要
为了综合反映水库水位高程、水位变化速率、水位特定高程三方面因素对水库地震活动的影响,引入模糊数学方法,定义水库水位从属函数,并结合水库地震的流体扩散机制假设,讨论了从属函数阈值选取和水体对水库地震活动的影响时间等问题。在此基础上,给出了一种研究水位变化与地震活动之间关系的定量方法,并使用该方法研究了浙江珊溪、福建水口、广东新丰江等三个水库地震与水位的关系。结果表明,水库蓄水初期水位是影响库区地震活动的主要外因,但三个水库的影响时间是有差别的,新丰江水库约为6年,水口水库约为5年,珊溪水库约为4年。
The available studies have shown that the three factors:reservoir water level elevation,water level change rate and specific water level elevation can affect the reservoir seismic activity.In order to comprehensively discuss the three factors,we introduce the fuzzy mathematical methods,define the membership function of the reservoir water level and consider the fluid diffusion mechanism hypothesis of reservoir earthquake,and then discuss how to select a subordinate function threshold,and how long that the water will affect the seismic activity.On this basis,a quantitative study method for the relation between the water level changes and seismic activity is given.With the method we studied the relation between earthquakes and the water level of three reservoirs in Shanxi Zhejiang,Shuikou Fujian,Xinfengjiang Guangdong.The results show that the initial water level of reservoir is the main external factor affecting seismic activity in the reservoir area,but the impact time of three reservoirs are different that in Xinfengjiang Reservoir is about six years,the Shuikou Reservoir about five years,Shanxi Reservoir about 4 years.
