| 摘 要： | 震动图（ShakeMap）是描绘地震发生之后地震动分布情况的一种工具，它显示的是地震产生的地面运动和可能的烈度破坏情况.本文的研究重点是如何实现用计算机自动绘制震动图，主要选择了峰值地面加速度等值图、仪器烈度分布图为研究对象.并对如何确定强震动质心、如何在台站稀疏地区估计地面运动加速度值、如何进行场地校正、如何将PGA/PGV转换为仪器烈度值做了深入的研究.

| Abstract: | ShakeMap is a tool used to portray the extent of potentially damaging shaking following an earthquake,mainly comprise maps about the spatial distribution of peak ground motions(Acceleration,Velocity) as well as a map of instrumentally-derived intensity map.How to generate ShakeMap automatically by computer is the key target here.We mainly study the rapid generation system of Peak Ground Acceleration and Velocity maps and rapid instrumental intensity maps.Many key problems of rapid generation of ShakeMaps,such as how to determine strong motion centroid,how to estimate ground motion in the sparse areas,how to make site corrections,how to convert Peak Acceleration and Velocity to Instrumental Intensity and so on are discussed in detail. |
