| Abstract: | The segmental tunnelling for Shanghai Rail Transit Line 11 will cross under Shanghai-Nanjing Railway and to meet the requirements for safe operation of the latter, the heave and settlement of the railway foundation and the rail are controlled to a very small range, based on the analysis of the hydrological and geological conditions of the site, and accurate setting and control of the soil pressure, driving speed, simultaneous grouting, alignment, etc., with details of the technical measures for the whole process of tunnelling across the railway, and proposed protection for its normal operation. |
