大断面黄土隧道的流变特性分析

Analysis of rheology characteristics of bridge-tunnel transition section in high-speed railway

以某黄土隧道过渡段为工程背景,采用结构分析软件ANSYS建立了过渡段三维实体有限元模型,对过渡段各断面及桥台进行了流变分析,该分析结果对于同类型黄土隧道过渡段的结构设计、流变特性研究有一定借鉴意义。

Taking a bridge-tunnel transition section as engineering background and using ANSYS software, a three-dimensional finite element model is established. Based on the model, theological analysis and track irregularity analysis are carried out.
