| 摘 要： | 本文在对多次地震震害资料进行研究分析的基础上,对其中符合现代隔震原理或思想的震而不倒的现象进行了分析,并将其划归为5类:(1)柱基“铰结”隔震消能;(2)结构底部柔性防潮层或薄弱层滑移隔震;(3)殿基、墙基或塔基滑移隔震消能;(4)柔性地基隔震消能;(5)采用长周期柔性结构。针对每一类情况分别进行了剖析,并列举了一系列震害实例。最后对现代隔震技术发展中所存在的问题及发展方向提出了看法。

| Abstract: | Based on the study of previous results about earthquake damages, the seismic isolation phenomenon is studied in this paper. We found that the following 5 types of seismic isolation cases: (1) plinth and column with flexible joint; (2) flexible or soft layer set at the foundation of the buildings; (3) displacement of base platform, towers or palaces of the buildings, which dissipates energy; (4) soft ground; (5) flexible structures with long period. In this paper, each case is analyzed based on the facts from earthquake damage investigation. Some problems about the development and the application of the seismic isolation technology are discussed. |
