摘　　要：本文结合郑西铁路客运专线张茅隧道2号斜井的防排水施工,按照客运专线隧道防排水设计思路,并考虑到影响隧道防排水结构设计的因素,形成一套有效的隧道防排水施工工艺,该方法有效地解决了大断面富水段黄土隧道施工中存在诸多技术难题,确保施工期间洞内排水快捷、安全、流畅。This paper combines the waterproof and drainage construction of No.2 inclined shaft of Zhangmao Tunnel of Zhengzhou-Xi＇an Railway Passenger Dedicated Line, according to the design idea of waterproofing and drainage of passenger dedicated tunnel, and taking into account the factors affecting the design of tunnel waterproofing and drainage structure, forms an effective tunnel waterproofing and drainage construction process. The construction process effectively solves many technical problems in the construction of the loess tunnel in the large section water-rich section and ensures that the drainage inside the cave is fast, safe and smooth during construction.
