摘　　要：本文对天津西站至天津站地下直径线采用盾构法穿越狮子林桥的技术方案进行了介绍,运用数值模拟手段计算分析了盾构对桩基的影响,得出了直径线盾构穿越对狮子林桩基变形及内力的影响不是很大、工程技术方案可行的结论,研究成果对类似工程的设计和实施具有借鉴和指导意义。In this paper, underground diameter line of Tianjin West Railway Station to Tianjin Station shield tunneling through Shi-zi-lin bridge piles are presented, and related issues about engineering schemes are analyzed through numerical simulation. The analyses provide that the shield tunneling has less effects on piles foundation of Shizilin Bridge and technical scheme is feasible. The results can serve as reference and guidance for the design and construction of similar projects.
