碩士 === 國立臺灣科技大學 === 營建工程技術學系 === 83 === The traditional assumption of analyzing ground reaction curve and fracture zone during tunnel excavation is that the tunnel behavior is under plane strain condition.However,the tunnel behavior during excavation should be three-dimensional.In order to further understand the mechanicsms of tunnel excavation,a three-dimensional simulation and analysis of tunnel excavation is attempted in the research.The minimum numerical simulation boundary and process of tunnel excavation is investigated atirst.Then,the reasonable numerical process is built in order to predict the tendency of the fracture zone,and the interaction of the support system and rock mass.Finally,the prediction of three- dimensional numerical analysis and the field monitoring data is compared.
