The impact of the excavation of the foundation pits of the west ventilation tunnel and the station of Chegongmiao〖JP〗 comprehensive transportation hub on Line 11 of Shenzhen Metro on the existing tunnel of Line 1 of Shenzhen Metro is analyzed in the paper. The rule of the deformation of the existing tunnel induced by the excavation of the foundation pits, as well as the consolidation effect of the jet grouting piles, is analyzed by means of threedimensional finite element program ABAQUS. Furthermore, the deformation of the existing tunnel is analyzed on basis of the measured data. It is concluded that the jet grouting consolidation can effectively reduce the uplift displacement of the existing tunnel.
