沉管隧道有限元与等效质点抗震分析比较
|
摘要
介绍了等效质点—弹簧模型和三维动态有限元方法在沉管隧道抗震分析中的发展和应用,结合天津海河沉管工程的例子,介绍了两种方法的基本原理、模型建立方法、模型简化方法、参数取值方法和实现步骤,最后通过比较两种方法中地震波的入射角度、接头最大轴向变形和接头最大横向剪切变形等计算结果,了解两种方法各自的的优缺点和适用范围。不仅对天津海河沉管工程项目开展有参考价值,同时得到的普遍性规律还可以为今后类似工程项目的抗震分析提供参考。
The development and application of equivalent mass-spring model and three-dimensional dynamic finite element method are introduced in immersed tube tunnel seismic analysis,taking Tianjin Haihe immersed tube tunnel project as an example,the basic principle,modeling method,model simplification,parameter method,implementation steps of the two methods are introduced,finally,to understand the advantages,disadvantages and scope of application by comparing the results obtained from two methods,such as the angle of incidence of seismic waves,maximum axial deformation of joints and maximum transverse shear deformation of joints.This study not only has a reference value for the project,its general principles can also be used as reference for similar projects in the future.
