国外已有许多国家都在研究一种新的建筑物抗震技术——避震装置,以避免或减轻地震威胁。其基本原理是在建筑物与地基之间增设橡胶等缓冲装置,以此来吸收地震对建筑物起破坏作用的能量。将建筑物与地基隔离开,则地震力将不会传导给建筑物,使建筑物得到安全。其方法是在基础和上部构造物之间,在水平方向设置柔软的“弹簧”即隔 Many countries in the world have been studying a new type of building seismic technology - shock absorbers to avoid or reduce the earthquake threat. The basic principle is to add a cushioning device such as rubber between the building and the foundation so as to absorb the energy that the earthquake damages the building. Separating the building from the foundation, the seismic forces will not be transmitted to the building, making the building safe. The method is to set a soft “spring” between the base and the upper structure in the horizontal direction.
