隧道结构抗震分析方法现状与进展
|
摘要
我国隧道及地下结构目前主要采用地震系数法、反应位移法和动力分析法三种方法进行抗震计算。文章总结这三种方法的原理和特点及其各自的适用性,并结合作者的研究成果,提出修正地震系数法与广义反应位移法。分析结果表明,修正地震系数法能够对传统地震系数法计算埋深进行合理修正,计算结果安全合理;广义反应位移法则扩展了反应位移法的应用范围,使其能适用于非均匀地层。两种改进分析方法具有合理性与适用性,可以为隧道结构抗震分析提供参考。
Seismic coefficient method,seismic deformation method and dynamic analysis method are mainly used in seismic calculation of tunnel and underground structure in China. The theory,characteristics and applicability of the above three methods are summarized,and then modified seismic coefficient method and generalized seismic deformation method are put forward. The results show that the modified coefficient method redefines the calculation buried depth of tunnel which leads to more rational and safer calculation results; the generalized seismic deformation method enlarges the application range of traditional seismic deformation method and it is suitable for irregular ground. The two optimization methods are of rationality and applicability and they will be helpful for seismic analysis of tunnel structures.
