| 摘 要： | 现行中国地震烈度表中,给出了Ⅴ度以上烈度区水平向地面运动峰值加速度（PGA）和峰值速度（PGV）两个物理参数与地震烈度的参考关系。当分别用PGA和PGV计算仪器烈度时,计算结果与现场调查烈度相符率很低。文中提出了基于相符率的加权方案,利用PGA和PGV综合评定烈度。评定结果表明,相符率有较大提高,说明该方法能有效地使仪器烈度更加接近宏观烈度。

| Abstract: | The current China Seismic Intensity Table gives the relationship between the two physical parameters, PGA and PGV of horizontal ground motion, and the seismic intensity for seismic area with intensity over V degree. However, when PGA and PGV are separately used to calculate the instrument intensity, there are usually some differences between calculation results and related field survey intensities. Therefore, One weighting method using both PGA and PGV to evaluate the intensity is proposed in this paper. The results indicate that it can make much improvement, i.e. making the instrument intensity much closer to the filed investigated intensity. |
