Reinforcement Measures of Shield Tunnel undercrossing Existing Railway Subgrade |
| |
| Abstract: | Based on the engineering of Liufucun entry-exit Line section of Luoyang Urban Rail Transit Line 2 undercrossing Luoyang—Yiyang Railway and Jiaozuo—Liuzhou Railway at short distance, taking into account the economy, safety and construction period of the project comprehensively, the corresponding reinforcement protective measures for railway rails, subgrade and catenary columns are put forward. The in-site monitoring results also proved the advantages and feasibility of the scheme for catenary pillar protection. The construction difficulties faced by the actual project in controlling the deformation of existing railway rails, subgrade and catenary were solved |
