【摘要】 近年来,地下涵管结构的应用越来越广泛,其抗震问题日益受到人们的重视,但是在这方面的分析相对较少。现针对受地震影响较大的浅埋涵管结构,概述了涵管结构的震害、地震反应特点、抗震分析方法,然后从地下结构的众多抗震分析实用方法中,列出了几种适合浅埋涵管结构抗震分析的实用方法,并对几种方法进行简单的分析比较,提出在不同的设计阶段应该采用不同的设计方法。更多还原

【Abstract】 In recent years, underground culvert structures are widely applied and more and more people are concerned its anti-seismic performance. The paper summarizes the earthquake damage, the characteristics of earthquake response and the antiseismic analysis method on underground structure. Several methods of anti-seismic research of culvert structure are listed, and are simply compared between. Finally, the methods that different design methods should be select at different design stage are suggested.更多还原
