Abstract:

The influence of the boring of largediameter shield machines on the longitudinal displacement, antifloating performance and lining structure of the existing Metro running tunnel is obtained by means of simulation of the twice passing of the large slurry shield machines underneath the existing Metro running tunnel. Consolidation measures are proposed on basis of the calculation and analysis results to minimize the influence on the existing Metro running tunnel so as to protect the Metro running tunnel from being damaged.
