摘要:
地铁车站换乘改造时，需要确保既有运营车站的结构安全和运营安全。以合肥轨道交通1号线云谷路站侧墙改造为例，提出了一种一次性凿除单个开洞的侧墙改造方案，并采用三维有限元软件计算分析了各工况下既有车站的内力重分布及变形情况。验算结果表明，所提出的改造方案可满足既有车站结构安全要求。
Abstracts:
When reconstructing metro stations for interchange, it is necessary to ensure the structural safety and operational safety of the existing operation station. Taking Hefei Rail Transit Line 1 Yungu Road Station side wall reconstruction as an example, a reconstruction scheme of side wall opening single hole at one time is proposed, and three-dimensional finite element software is adopted to calculate and analyze the existing station internal force redistribution and deformation under various working conditions. The checking calculation results show that the proposed reconstruction scheme can meet the structural safety requirements of the existing station.
