新建车站围护结构对既有车站的偏压影响分析及对策研究

针对新建车站围护结构对既有车站偏压影响,文章利用有限元软件,结合成都地铁某线实例,通过建模计算分析基坑开挖对既有线结构的竖向及水平位移,并结合规范对既有车站结构的影响程度进行了评价。

In view of the influence of the enclosure structure of the new station on the bias of the existing station,this paper uses the finite element software,combined with an example of a Chengdu subway line,through modeling and calculation to analyze the vertical and horizontal displacement of the foundation pit excavation on the existing line structure.In accordance with the relevant code,the influence degree of the existing station structure is evaluated.
