In the tunnel project construction process, excavated tunnel construction is very easy to cause great interference to formation, and because the depth of the tunnel excavation is not enough, it is easily lead to the automatic dispersion and adjustment of foundation. In order to ensure the stability of rock affected by the construction and effectively control the upper stratum with settlement, it will conduct construction in shallow lots by long pipe roof, advanced small catheter and other technologies. Based on this, the article discusses the construction management techniques of large pipe shed in the tunnel project.%在隧道工程的施工过程中，暗挖隧道施工很容易对地层造成非常大的干扰，因隧道暗挖的深度不深，容易导致地基应力自动的进行分散和调整。为了确保受到施工影响岩层的稳定性，对出现沉降的上部地层进行有效的控制，会在浅埋地段使用长管棚、超前小导管等技术进行施工。基于此本文对隧道工程中大管棚施工管理技术进行探讨。
