The paper has presented a physical oil production technology by artificial earthquake, that is, vibration waves are caused in the oil - bearing formation, resulting in a series of vibration effects, there - fore, oil productivity or water injectivity is increased
摘要人工地震採油是通過地面可調頻振源進行一定頻率的振動，產生振動波，在油層發生一系列的波動效應，達到增產增注目的的一項物理法採油技術。 -
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。
