摘　　要：以渝昆高铁引入昆明枢纽工程隧道为研究对象,探讨了悬臂掘进施工的截割方式及施工工艺流程,并通过数值模拟和现场实测的方式探讨了隧道在采用悬臂掘进施工时的响应特性。从隧道的应力及变形情况看,其数值均处于规范要求范围内,且模拟值和实测值较为接近,说明隧道悬臂掘进施工有一定的合理性和可靠性。In this paper,the cutting method and construction process of cantilever tunneling are discussed,taking the tunnel from Chongqing-Kunming high-speed railway to Kunming Hub project as the research object,and the response characteristics of the tunnel under cantilever tunneling are discussed by means of numerical simulation and field measurement.From the view of the stress and deformation of the tunnel,the values are within the range required by the specification,and the simulated values are close to the measured values,which indicates that the tunnel is reasonable and effective during the construction of the cantilever.
