随着经济的发展以及交通运输业的扩展,大跨度的桥梁成为一种发展趋势,数量日益增多。作为桥梁工程的一种重要形式,大跨度桥梁的抗震能力高低与桥梁的破坏程度息息相关。在大跨度桥梁抗震设计中,合理的结构形式和成功的抗震设计可以有效提高大跨度桥梁的防震和抗震效果,从而减轻甚至避免地震的破坏。基于此,本文主要对大跨度桥梁抗震设计实用方法进行分析。
With the economic development and the expansion of the transportation industry, the long-span bridge has become a trend of development with an increasing number. As an important form of bridge engineering, the seismic capacity of long-span bridges is closely related to the degree of damage to the bridges. In the aseismic design of long-span bridges, a reasonable structure and successful seismic design can effectively improve the anti-seismic and anti-seismic effects of long-span bridges so as to reduce or even avoid the damage caused by the earthquake. Based on this, this paper analyzes the practical methods of aseismic design of long-span bridges.
