摘要:
［目的］上海市轨道交通宝山路站为提高列车通过能力和降低安全风险，需进行线路接轨改造，相应的车站结构也需改造加固。由此梳理出车站结构改造设计中的主要问题、处理方法和对运营的影响控制。［方法］介绍了宝山路站改造工程的概况，阐述了设计原则，确认了设计方法，开展了超限结构性能化设计来验证加固改造后的抗震性能，并提出了针对宝山路站的结构自适性加固改造方案，分析了设计过程中遇到的重难点和解决方法；为保证施工期间车站正常运营，提出了分阶段的施工组织计划。［结果及结论］宝山路站经过改造后，满足了增加股道的要求。通过结构加固，车站的抗震性能可以满足现行规范的要求。车站结构工程的分阶段实施能有效降低对车站运营的影响。
Abstracts:
［Objective］ To enhance train throughput capacity and reduce safety risk at Baoshan Road Station in Shanghai rail transit, a track joint-rail renovation is necessary, requiring concurrent reinforcement of station structure. Thus the key issues in station structure renovation and design, countermeasures, and control on operational impact are sorted.［Method］ The overview of Baoshan Road Station renovation project is presented, outlining design principles and confirming the design methodology. A code-exceeding structural performance design is conducted to validate the seismic resistance after reinforcement, and the tailored adaptive reinforcement plan for Baoshan Road Station structure is proposed, addressing critical challenges encountered during the design process along with their solutions. To ensure normal station operation during construction period, a phased construction organization plan is introduced.［Result & Conclusion］ The renovated Baoshan Road Station meets the requirements of additional tracks. Through structural reinforcement, the station seismic resistance can meet requirements of current regulations. Phased station structure engineering can effectively lower various impacts on station operation.
