| Earthquake is one of the most destructive disasters to human society. Data show thatpersonnel casualty in the earthquake is mainly caused by the damage of buildings, so one ofthe important measures in disaster prevention and reduction is to strengthen the seismicprevention of building. Nowadays, isolation technique is the most effective approach toreduce earthquake hazard. Isolation technique extends the basic period of side structuralvibration and reduces the action of horizontal earthquake movement on superstructure bysetting horizontal soft layer between superstructure and base.This article integrates the key technology projects of Guangdong Province-"Application and research of new isolation and damping technique in Guangdong ScienceCentre" and gives a study on some items. It mainly resolves design and constructionproblems during the application of base isolation technique in the Square E of GuangdongScience Centre. The article consists of the following parts:1. Give a brief introduction to the application background and structural characteristicsof isolation technique adopted in the Square E of Guandong Science Centre.2. Combining the installment process of isolation bearings, the article gives a studyon the installment technology of isolation bearings in the mega steel frame structure of theSquare E, resolves some problems in the construction and compares the difference ofisolation construction in steel and concrete structure.3. Test the mechanics performance of lead rubber isolation bearings, which is of thebiggest diameter in the country and lead rubber compound damper bearing applied in thisproject. This article also studies the testing methods of horizontal performance of thedamper of new type.4. Besides, the article focuses on monitoring the distortion of the bearings in theconstruction process, including vertical distortion, horizontal distortion, partiality distortionetc. and analyzing the peculiarity and reasons of these distortions.
