【摘要】 本文在对活动断层的工程涵义进行了简要分析后,讨论了断层物质测年的工程应用进展及其断层活动时代鉴定问题,并就如何加强中强地震发震构造判别、应用地震地质资料评估大地震年平均发生率、以及活动断层地表断错位移的概率评价等问题作了初步探讨。更多还原

【Abstract】 Base on the definition of active fault and its meaning to engineers, this paper reviews some geological aspects and problems, such as the application of dating results in determination of active faulting ages, seismo-tectonics background studying on moderate-strong earthquakes, estimating earthquake recurrence from geological investigation, and probabilistic evaluation of the ground offset of active fault.更多还原
