摘　　要：贵南高速铁路A隧道全长10.130 km,结合A隧道几年来测量实践,通过隧道沉降观测技术的应用,为预估无砟轨道施工是否具备条件、保证铁路开通运营后列车平稳运行提供可靠的数据支撑,也可在其他长隧道施工中推广应用。Guiyang-Nanning high-speed Railway A tunnel is 10.130 km long.The study combines with the measurement practice of tunnel A in recent years,applies tunnel settlement observation technology,and provides reliable data support for predicting whether the construction of ballastless track has the conditions and ensuring the smooth operation of trains after the railway under operation.It can also be popularized and applied in the construction of other long tunnels.
