介绍大跨度桥梁的抗震设计研究进展,并提出了在桥梁抗震的设计过程中应遵循的一些设计原则和桥梁减、隔震的有效措施,指出合理的结构形式的抗震设计可以大大的减轻甚至避免震害的产生,从而能很好地达到桥梁结构的防震和抗震效果。
The research progress of anti-seismic design of long-span bridges is introduced. Some design principles to be followed in bridge anti-seismic design and effective measures of reducing and isolating bridges are pointed out. It is pointed out that the rational design of anti-seismic structures can be greatly reduced or even avoided Earthquake damage, which can well achieve the bridge structure of earthquake and seismic effects.
