地震活动性三分维的综合研究
|
摘要
从地震的混沌性现点出发，对地震时、空、强的分布进行分数维计算，寻找其变化规律。通过与断层维数进行对比，统计结果发现，三者同时与断层维数有关。依据简单的物理模型和假定，对这一现象进行了理论解释。同时还进行了岩石压裂实验，实验证明岩石裂隙的维数在2．5级左右，与假设条件及理论分析结果相一致。
The authors have calculated fractional dimensions of earthquake time,space and magnitude distribution from the view of seismic chaos,and found the varied regularity. Campared to the fault dimension, the statistical result shows that the earthquake time, space and magnitude are related With the fault dimension. The authors have explained theoretically the phenomenon according to the simple physical model, and they also conduct rock -breaking test which shows the rock-fracture dimension is about 2. 5 which consists with the result of theoretical analysis.
