城市地下交通工程普遍存在施工难度大、空间狭小、周边紧邻建筑物、道路、市政管线等特点，在地铁站出入口工程中显得尤为突出。如何在复杂的施工条件下完成出入口暗挖施工中的支护工作，是地铁施工必须面对和解决的问题。通过阐述西安地铁2号线永宁门站IV号出入口工程超大管棚支护技术的设计思路，结合监测数据分析，说明了浅埋暗挖支护技术综合应用的效果。

The city underground construction project has the characteristics of difficult construction, narrow space, the close construction, road and municipal pipeline, which are quite obvious in the construction of subway station exit and entrance. How to complete the subway station exit and entrance shallow underground excavation support work in such complicated situation is the issue which has to be faced and solved. This paper shows the effects of shallow underground excavation support technology integrated application by explaining the design thought of oversized pipe shed support technology in Yongningmen Station IV exit and entrance in Xi’ an Subway Line 2 and analyzing the supervision date.
