The beginning and development of monitoring and predicting earthquake from 1970 to 1976 in sichuan province and the typical example for the protecting against earthquakes are described in this paper
摘要記述了1970 ~ 1976年四川地震群測群防的興起和發展，介紹了四川群測群防、專群結合預測預報地震的典型事例，特別對松潘平武7 . 2級地震預測預報群測群防的作用作了反映。Considering the ratio of non strike - slip faults and non mainshock - aftershock, yunnan area can be divided into four subareas with different characteristics, which are strike - slip mainshock - aftershock in central yunnan ( a1 ), incline - slip swarm in northwestern yunnan ( a2 ), strike - slip double shock in western yunnan ( b1 ) and quasi - strike - slip mainshock - aftershock in southwestern yunnan ( b2 ), respectively
考慮到非走滑地震斷層和非主餘震型地震序列所佔的比例，可以將雲南地區劃分為4個具有不同特點的分區：滇中（ a1 ）走滑主餘震型區、滇西北（ a2 ）斜滑震群型區、滇西（ b1 ）走滑雙震型區和滇西南（ b2 ）準走滑主餘震型區。Several important conclusions are gained by the analysis of push - over method and quasi - static reversal load pattern to a reinforced concrete structure : under the two earthquakes, the responses of structure are more serious than the responses under single earthquake, by the conclusion, it is not rationality that structure ' s earthquake damage prediction under single earthquake ; the main - after earthquake action is different from fore - main earthquake action under the same earthquake magnitude combination ; the push - over analysis to the structure is convenient and utility, it also reflects the response and performance of structure under the earthquake, so the method ' s development future is wide. based on the research of the former scholars, some means of structure resisting earthquake are introduced in the last part of this thesis, and the result of earthquake damage prediction for the planning area of quanzhou city is given
通過對一鋼筋混凝土結構進行push - over分析與擬靜力循環往復加載分析，得到了一些重要結論：在兩次地震動作用下，結構物的反應比僅考慮一次地震動作用時的反應要嚴重的多，從而說明傳統上僅僅考慮一次地震動作用的建築物震害預測是不合理的：即使在同震級組合的兩次地震作用下，前震主震型、主震餘震型地震對結構物產生的破壞作用也是不盡相同的；對結構物進行靜力彈塑性分析的方法（ push - over方法）簡便實用，並能較準確地反映大震下結構的一般性能和反應，再一次的證明了該方法具有廣闊的發展前景；根據前人的研究成果，在本文的最後，簡單的介紹了一些結構物抵禦多次地震破壞作用的方法，並給出了泉州市規劃區內鋼筋混凝土框架結構群體震害預測的結果。
