摘要
桥梁是"生命线工程的"重要组成部分,通过对国内外地震灾害的研究表明,震区桥梁的损坏坍塌,不仅会阻碍救灾行动,而且影响灾后的重建工作。因此,对于那些震后的紧急救援和震后经济恢复中具有重要地位的桥梁,要求比较严格,应不发生震害或震后可快速恢复后即可使用,本文将针对桥梁结构的震害及抗震设计方法进行探讨。
Bridge is an important part of the "lifeline engineering". The study on the domestic and international earthquake research suggests that the damage and collapse of the bridge in earthquake zone will not only hamper rehef efforts, and also affect the post-disaster reconstruction work. Therefore, it has more stringent requirements for the bridge which has an important position in emergency relief and post-earthquake economic recovery after the earthquake, and it should not be damaged by earthquake or it can be recovery quickly after the earthquake. This article will discussed the damage of bridge structure in earthquake and the seismic design methods.
