影响断层带再活动的一些因素的实验研究

EXPERIMENTAL RESEARCH ON SOME FACTORS AFFECTING THE REACTIVATION OF FAULTS

摘要:

很多地震发生在活动断层上。但断层带是否活动并不是一成不变的。目前,在没有大量实测资料的情况下,我们往往还要推断哪些断层是易于活动的。实验与计算结果表明,影响断层再活动的因素为力的方向、力的大小,断层带厚度,断层带物质的力学性质等。这些结果将有助于我们推测活断层。

Abstract:

A number of earthquakes are associated with active faults. In the absence of measuring data, we intend to deduce which have faults are apt to be active. Based on the experimental and measured results, it is shown that direction and magnitude of external stress field as well as thickness and strength of faults are main factors which have affected the reactivation of faults.
