断裂带中的流体活动及其作用

Fluid Involvement in Active Fault Zone

摘要:

大量证据表明活动断裂带中存在大量流体,不仅可以造成断裂带强度的变化,而且可以导致有效正应力减小,进而诱发地震。在野外观察与模拟的基础上,许多模式被用来解释这一现象。本文简要介绍了有关断裂带特征和分类、流体的来源和运动,以及流体对断裂带的影响和对地震的触发作用等方面的研究进展。

Abstract:

In active fault zone there is a lot fluid which may not only alter the strength of fault zone, but also change stress and trigger earthquake. In this paper the recently research on the characteristics and types of fault zone,as well as source and fluxion of the fluid in thd zone are described,the discussion on influence of the fluid and the role of the fluid in earthquake pregaration process are also introduced.
