黄陵坡隧道仰拱渗漏水病害整治技术研究

Treatment Technology Study for Water Leakage Disease of Inverted Arch in Huanglingpo Tunnel

在我国水资源丰富的西南地区,高速铁路隧道施工完成后,受地质原因等各种因素的影响,会产生仰拱渗漏水病害,长期出水将对无砟轨道和运营安全带来极大的安全隐患,因此对于仰拱水害的整治必须高度重视。本文分析了成贵铁路黄陵坡隧道仰拱渗漏水的原因,并结合病害整治施工实际,详细介绍了整治的方法、施工要点以及注意事项。通过严格认真的实施,取得了良好的效果,可为今后类似工程提供借鉴。

Water resources are rich in the southwest of China, owing to the influence of various factors, such as geological reasons, the water leakage of the inverted arch will be occurred after completing the construction of high-speed railway tunnel. Long-term water leakage will bring great risks to ballastless track and operation safety, so it is necessary to pay great attention to the water damage treatment of the inverted arch. This paper analyzed the causes of water leakage disease for inverted arch in Huangiingpo Tunnel of Chengdu-Guiyang High-speed Railway, and combined with the practice of disease control construction, the treatment method, key points of construction and matters needing attention were introduced in detail. Through strict and conscientious implementation, good results were achieved, which could provide reference for similar projects in the future.
