云南强震动流动观测发展及相关问题讨论

Development of Mobile Observations for Strong Motion Observation in Yunnan and the Discussion of its Related Issues

简要介绍了云南强震动流动观测的发展历程和省内6次典型震例的强震动流动观测及特点,并总结和探讨了强震动流动观测时应该注意的相关问题。基于强震动观测应用及研究现状,建议加强并拓展强震动流动观测工作,适时建立强震动流动观测系列的规程、规范,不仅要把流动观测作为弥补固定台网不足以增强捕获近场强震动记录能力的辅助手段,更要把强震动流动观测作为解决地震基础研究与地震工程应用难题的一个重要手段。

The developing course of mobile strong ground motion observations and some exploration and trial works in Yunnan are briefly introduced in the paper Six typical earthquake examples and their records are showed The relevant noteworthy problems are discussed It is suggested that the series of the regulation and standard for the mobile strong motion observation should be timely established The temporary strong-motion observation is not only auxiliary mean to cover the shortage of the fixed network of strong ground motion observation to enhance their ability to capture the records near the field vibration,but also the main method and technology approach to solve problem of the basic research and engineering applications of advantage of huge experiment field of natural earthquakes
