地铁车站出入口标准段结构尺寸优化组合计算分析

Optimization analysis on dimension combination for standard subway exit structure members

地铁车站出入口是乘客进出车站及消防疏散的主要通道。出入口结构尺寸主要由建筑使用功能、覆土深度、地质条件及周边环境等因素制约。以福州地铁1号线工程为背景,进行结构设计与计算分析研究,通过对不同埋深条件下地铁车站出入口标准段结构尺寸的分析比选,得出合理的断面尺寸优化组合,以期为类似工程提供设计参考。

Subway exits are main access to station and main fire escape exit. The dimension of structure members on exits are determined by architectural function,cover depth,geo-condition and surrounding environment. Taking Fuzhou Line 1 project as an example,structural analysis and design are done and different dimension combinations are compared to get the optimized dimension combination and to provide reference for future projects.
