摘　　要：通过分析研究美国地质调查局和日本气象厅的仪器烈度算法,认为计算仪器烈度要综合考虑幅值、频谱、持时等地震动参数的影响,创新地提出了利用三分向合成加速度、速度计算仪器烈度,并通过汶川8.0级地震进行验证。结果表明,本文推荐的仪器烈度算法,其结果具有较高的准确性和可靠性,可为地震烈度速报提供参考。Strong motion observation is very important for the nuclear power plant, High-speed Rail and other important project. In this paper, the amplitude, frequency spectrum, duration of ground motion parameters are all considered, innovation land have put forward the new method of seismic intensity which is synthesized by three components, through the analysis of instrumental intensity method of the U.S. Geological Survey(USGS) and the Japan Meteorological Agency. This method is verified by the Wenchuan earthquake, which may provide useful references to seismic intensity rapid assessment.
