| Summary: | 碩士 === 中華大學 === 土木工程學系碩士班 === 91 === The New Austrian Tunneling Method (NATM) is particularly and used to design the rock tunnel construction in east Taiwan. However, it is systematically to used monitor of the convergence and deformation of tunnel. By the way, it can be made by the well headway with the tunnel’s excavation by changing the designing and executing to compare with monitor and design. Nevertheless, it is always lack of the evident methods for analysis and design.
The purpose of this study includes the application of the Convergence-Confinement Method and the New Explcit Method, the parameteric study by means of the regression analysis the obtained from one track tunnel’s measurements in the Taiwan, and the prediction of interaction between rock mass and support system in tunnel construction.
The content of this paper includes the introduction of the east Taiwan one track tunnel’s informations and bathylith of formationsts, the application of analytical calculation to the railway tunnel. According to the analytical calculations obtained, the displacements of pre-stage and of unsupported distance, the modulus of elasticity of rock mass, the pressure of support system, and the longitudinal deformation curve are particularly observed.
