摘　　要：随着人口的日益增长,地铁成为人们出行的首选,随着地铁线路的逐步延伸其满足了人们对出行的需求,然而新建地铁施工对既有地铁的影响问题已逐步暴露,工程困难成为地铁发展的制约因素。研究以天津地铁项目为例分析了新增顶管结构对既有车站的影响及保护措施。通过midas GTS有限元计算软件分析了对既有车站结构的影响结果,提出具体的风险工程保护措施及应急预案,可以在保证既有车站主体结构的安全及正常运营的情况下,有针对性地对天津及周边地区新增结构对既有车站的影响进行了分析,以期对工程项目实际施工起到指导作用。With the increasing population,subway has become the first choice for people to travel,and with the gradual extension of subway lines,it can meet people's travel needs.However,the impact of new subway construction on the existing subway has been gradually exposed,and engineering difficulties have become a restricting factor for the development of subway.Taking Tianjin Metro project as an example,this paper analyzes the influence of new pipe jacking structure on existing stations and its protection measures.midas GTS finite element calculation software was used to analyze the impact on the existing station structure,and specific risk engineering protection measures and emergency plans were proposed.Under the condition of ensuring the safety and normal operation of the main structure of the existing station,the impact of the new structure on the existing station in Tianjin and its surrounding areas was analyzed in a targeted way.In order to play a guiding role in the actual construction of the project.
