沉管接头简化方法及三维抗震有限元分析
|
摘要
介绍了沉管隧道抗震研究的国内外发展情况,运用沉管接头的非线性弹簧元简化模型和三维有限元建模的抗震分析思路,结合天津海河沉管工程实例,通过大型有限元软件建模,计算得到沉管接头在地震荷载作用下的变形和内力响应情况。不仅对项目开展起到参考价值,同时得到的普遍性规律还可以作为今后类似的工程项目提供参考。
Introduced is the development and application of immersed tube tunnel seismic research at home and abroad,using the nonlinear spring element simplified model of immersed tube joint and three-dimensional finite element modeling of the seismic analysis,taking Tianjin Haihe immersed tube tunnel project as an example,modeling and calculating are carried out to get the deformation and internal force responses of immersed tube joint through the finite element software.This project not only has a reference value,but its general principles can also be used as reference for future similar projects.
