活断层设防分析

Analysis on seismic fortification of active faults

我国是一个多地震的国家,活断层分布广泛。对活断层地震的防御通常采用避让和抗震设防设计两种手段。避让距离的确定和在抗震规范中如何考虑近场地震动的影响两方面的研究目前正是迫切需要解决的重要问题。文中主要针对这两方面的研究现状和发展前景做初步探讨。

There are many earthquakes and active faults are widely distributed in China . Two methods, avoiding active faults and earthquake-resistant design, are adopted to defend earthquakes accured in active faults. It is cur- rently urgent to solve the two important matters, determining the avoided distanse and how to consider the influence of the near-field ground motion. In this paper, the research and the development prospect of the above two matters are discussed.
