摘要/Abstract

摘要： 地下水化学组份的震前异常特征之一是异常形态多样,异常幅度不等,形态与幅度方面表现出复杂性。为揭示这种复杂性的实质,进行了水动力学模型实验研究。研究结果表明,脉冲状水化学异常信息在含水层系统中的迁移规律是复杂的,随着迁移距离的增大信息幅度的衰减是明显的,甚至异常形态也有变异。异常信息的这种变化特征还与含水层受力状态的不同有关。

关键词: 水化学异常, 水动力学模型, 实验研究

Abstract: The anomaly features of hydroehemieal components appeared before earthquakes consist of multiple forms,uneven amplitudes and complieated variations of the forms and amplitudes.To reveal the essence of the complexity,the experiments on hydrochemic model are carried out. The results indieate that the regularity of pulse hydroehemi-cal anomaly migration in the aquifer system is rather complicated. With increase of the migration distance,the information amplitude attenuates obviously,and even the anomaly forms are changed. These features of variation are also related with the stress state that the aquifer has been situated in.

Key words: Seismic hydroehemieal anomaly, Hydrodynamic model, Experimental study
