摘要：本文基于全国各地工程调研，对北京地区无柱大跨岛式车站结构选型进行分析，并重点针对变截面厚板方案存在痛点增加组合结构（顶板钢+混）方案比选。同时，本文对变截面厚板方案及组合结构方案空间效果、经济性等进行分析，以期能为相关工程提供一定技术支持。
Abstract: Based on engineering research across the country, this article analyzes the structural selection of column-free large-span island stations in Beijing, and focuses on the comparison and selection of composite structures (steel + concrete) for the variable crosssection thick plate scheme, which has potential problems. At the same time, this article analyzes the spatial effects and economic efficiency of the variable cross-section thick plate scheme and composite structure scheme, in order to provide technical support for related projects.
