摘要： 以某地铁车站的基坑为例，研究地表交通荷载作用下地铁车站基坑的稳定性。结果表明：采用现行规范进行预应力钢支撑设计，除可以承受计算的静载荷外，还有一定的能力承受振动荷载作用，并维持基坑的稳定性。在考虑周边地表交通荷载时，需严格按照既有规范进行基坑支护设计。预应力钢支撑施工时需特别注意支撑的结构、组装方式、施加预应力的方式和施加预应力的时间等对支护效果的影响。

Abstract: This paper presents a case study of the effect of surfaced traffic loads on the dynamic response of a subway train station supporting structures. The results show that: in addition to the design static load, the prestressed steel struts designed in accordance with the current code can still taking the vibration load and maintain the stability of the deep excavation. When considering the traffic load on the surrounding surface, it is necessary to design the deep excavation support structure in strictly accordance with the existing specifications. During the installation of the prestressed steel support, special attention should be paid to the influence of the supporting structure, assembling method, prestressing method and prestressing time on the supporting effect.

Key words: Subway Station, Deep Excavation, Supporting Structure, Surface Traffic Load
