Abstract
With the higher requirements for the safety, quality, environmental protection of construction and the increasingly growing labor costs, it is imperative to promote the mechanization of the tunnel construction. Pre-lining technology as a mechanized tunnel construction method between the shallow-buried tunneling method and the shield tunneling method, can not only rapid excavatemechanized, but also effectively control the ground subsidence. In this paper, the pre-lining technology was used to simulate the tunnelconstructionin weak surrounding rock, andground deformationwas also monitored. It was showedthat the vertical and horizontal displacements of the strata were small, alsowas the and the groove deformation, which can meet the requirements for tunnel construction. And pre-lining construction methodwas more advanced compared with the traditional mechanical pre-cutting method.
