The modification work of the subway #1 in Tianjin is the project reconstructed the stations and some tubes on the base of primary subway. The differential settlement at the juncture of new and old tubes must be controlled strictly for the sake of safety. The technique of high-pressure chemical churning piles is employed to consolidate the foundation. The consolidating means and thickness are determined by the result of FEM; by contrast to the measured data in-situ
the result of numerical calculation is testified to be proper and the design proposal is rational accordingly.
