摘要:
［目的］以北京地铁10号线西土城站换乘改造施工为例，对未预留换乘条件的既有地铁车站换乘改造施工方案展开研究。［方法］为满足与北京地铁昌南线换乘的要求，对既有1号线西土城站进行换乘改造。在既有地铁10号线西土城站站厅层侧墙开洞与换乘通道接驳；清空站厅层，全部改为付费区，闸机、安检移至各出入口地面厅或地下厅；在站厅层与站台层之间的楼板开洞增设自动扶梯、电梯等。此外，对站内施工区域的混凝土结构进行沉降变形监测，以控制侧墙破除、楼板开洞等站内改造施工作业对既有车站自身结构的影响，保证了北京地铁10号线西土城站换乘改造施工的安全和混凝土结构稳定。［结果及结论］建议在以后的地铁车站规划时,应具有一定的前瞻性,从城市轨道交通发展的大层面进行车站的结构设计,以充分预留出换乘空间。
Abstracts:
［Objective］ Taking the interchange renovation construction of Beijing Subway Line 10 Xitucheng Station as example, the construction scheme for interchange renovation in existing station without reserved transfer conditions is studied. ［Method］ To meet the interchange requirements with Beijing Subway Changnan Line, the existing Line 1 Xitucheng Station undergoes an interchange renovation. Openings are made on the side walls of this station concourse floor to connect with the interchange passage. The entire concourse level is cleared and converted into a paid area, with ticket gate and security inspection relocated to ground or underground halls at each entrance. Escalators and elevators are added by creating openings in the floor between the concourse and platform levels. Additionally, settlement deformation monitoring of the concrete structures in the station construction area is conducted to control the impact of activities such as side wall demolition and floor openings on existing station structure. This ensures the safety and stability of the concrete structure during the interchange renovation construction at Beijing Subway Line 10 Xitucheng Station. ［Result & Conclusion］ It is suggested to hold long-term foresight in future station planning, carry out station structure design from the macro-perspective of urban rail transit development, and preserve sufficient interchange space.
