Given the complexity of urban rail transit networks, it is inevitable to pass through existing or under construction projects during the design and construction of new underground projects. Based on a rail transit project in Chongqing, this study adopts the finite element method and combines with field monitoring to investigate the settlement and deformation rules of shield segments and inclined shafts during the construction process of the subway shield tunnel overpassing high-speed rail inclined passage. On this basis, the mutual effect between subway shield tunneling and construction passage of high-speed rail inclined shaft is revealed. The results show that during the construction of the shield tunnel’s overpassing the inclined shaft passage, the settlement of the shield segments will increase due to the existence of the inclined shaft passage. Additionally, the inclined shaft passage will appear upward displacement and deformation, which is proportional to the distance between the shield tunnel construction intervals. The research results can provide certain technical references for the construction of similar projects.
