随着我国经济的不断发展,基础设施进入了高峰期,而我国作为地震频发期的地区,大跨度桥梁在地震中一旦遭到破坏,不但造成经济损失,而且危害人们的生命安全,并且影响了后期救援工作。所以加强双塔斜拉桥抗震设计,加强抗震能力具有极其重要的现实意义。 As China’s economy continues to develop, infrastructure has entered a peak period. As a region where the earthquake is frequent, the long-span bridge, once destroyed in the earthquake, not only causes economic loss but also endangers people’s lives and affects After the rescue work. Therefore, it is of extremely important practical significance to enhance the seismic design of double-tower cable-stayed bridges and strengthen the seismic capability.
