| Abstract: |
This paper mainly relies on the project of Hangzhou Metro Line 5 obliquely crossing underneath Zijingang Road Tunnel. The paper analyzes the influence of the shield position on the vertical displacement and torsion of the existing tunnel. Grouting pressure and stratum reinforcement conditions are also considered. And find the law of the influence of various construction technical parameters on deformation under different excavation stages. Then give corresponding advice for the project and provide guidance and reference for similar projects in the future. |
