地震工程的跨世纪发展趋势

本文对国内外近几年来发生的几次地震所提供的经验教训进行了简要的评述，指出近场地震中的高强度速度脉冲的破坏作用在抗震设计中应该给予足够的重视。在许多震害实例中还可以发现高层建筑、高架桥梁等基础设施和工业设备的地震保护尚存在许多薄弱的环节。在强烈地震中，这些结构和设施的破坏所造成的经济损失和对社会的冲击是很大的。为了最大限度地减轻地震灾害，应该将防震减灾作为一个系统工程来加以研究，应用现代化的高科技手段和灾害管理技术发展经济高效的减灾措施，在地震学家、土木工程师、工业和材料专家、经济师、社会科学和管理专家的共同参与下，使下一世纪的抗震防灾工程不断取得新的突破。

Development Trend of Earthquake Engineering toward New Century

This paper briefs the experiences and lessons learning from the destructive earthquakes in China and abroad in recent years.It is pointed out that the damage action of the large velocity impulse in ground motion in near field should be considered in seismic design.Numerous earthquake examples show that there are many weakness in aspects of earthquake protection of high rise buildings,overpass bridges and other infrastructures and industry facilities.Damaging of these structures and facilities could result in tremendous economic losses and social impact.It is stressed that earthquake disaster mitigation being as a scientific and engineering Branch should be studies by systematic engineering methodology in order to reduce earthquake disaster as possible.In addition,this paper stresses that in order to acquire new breakthrough in earthquake engineering field in the next century,it is very important to explore high performance low cost earthquake protection measures and to promote close cooperation among seismologist,civil engineer,industry and material expert,social scientist,economist and management expert.
