Abstract: Based on a series of exploration and practice in the process of tunnel construction of Haoji railway, the management measures about onsite check and optimization of construction drawings, change design, headmans responsibility system for project quality, monitoring measurement, and application of tunnel tooling equipment were presented. These measures could provide system support for the construction of the tunnel project safely and rapidly. In the aspect of design optimization, design parameters optimization about the inner contour of tunnel structure, the type of inverted arch structure and the supporting structure of auxiliary tunnel were introduced. These optimization measures could ensure the safety of tunnel supporting structure and the rationality of project cost. In the aspect of technical innovation, the type of steel frame of initial support, combination form of initial support, the type of composite lining structure, new type of initial support structure of resistance limiter, and large section horseshoe shield were introduced. Moreover, the scientificity and rationality of the tunnel support structure were guaranteed effectively through scientific research and experimental research. The above mentioned management measures, design optimizations, technological innovations can provide reference for tunnel construction in the future.
