| Abstract: | Taking the project of the section tunnel between Jinjihuxi Station and Dongfangzhimen Station of Suzhou Metro Line 3 passing underneath Line 1 as an example, protective measures of the installation of rail protections for anti-removal and the traffic control were put forward to prevent the track sinking of Line 1 and to reduce the influence of settlement on the safety of vehicle operation. The scope and detailed installation process of rail protections for anti-removal were introduced, and the feasibility of the technology was verified by field monitoring, providing the guidance for similar projects in the future. |
