混凝土结构基础隔震技术及其应用

Vibration isolation technology and its application to concrete structure foundation

为使输入上部结构的地震能量和加速度大为降低,从而大幅地提高建筑结构对强烈地震的防御能力,在工程实践中常通过水平刚度低且具有一定阻尼的隔震器在上部结构与基础之间实现柔性连接,这便是混凝土结构基础隔震技术。就基础隔震技术的基本原理、隔震器的基本要求、基础隔震技术的优点及其工程应用情况作了较为详细的阐述,为基础隔震技术的应用和推广提供参考。

In order to reduce possible seismic energy and acceleration transmitted to upper part of structure and improve seismic resistant capability of the building, it is usually, in engineering practice, to use vibration isolators, which have low stiffness and some damping in horizontal direction, to realize soft connection between upper part of structure and foundation. It can be called vibration isolation technology of reinforced concrete structure foundation. The paper expounded principle of structure foundation vibration isolation technology, the basic requirements of vibration isolators, advantages of foundation vibration isolation technology as well as application of foundation vibration isolation technology. It is sure that the present findings could give a reference to application and popularizalion of foundation vibration isolation technology.
