The shield tunnel of the Kunming subway crosses beneath the Kun-Shi Railway. Due to\nthe high requirements of railway track for settlement control, this article proposes the following\ntechnical measures for controlling the settlement based on the analysis of risks arising from the\nshield crossing railway: (1) Reinforcing the stratum of the region crossed by the shield in advance to\nachieve high stability; (2) Using a reinforced segment for the shield tunnel and increasing reserved\ngrouting holes for construction; (3) Reasonably configuring resources, optimizing construction\nparameters, strengthening monitoring and information management during the shield crossing.\nIn strict accordance with the construction plan, the shield successfully and safely crossed beneath the\nKun-Shi Railway; this provides experience that can be used in similar projects in the future.
