Abstract：Research purposes ： The surrounding environment of the deep foundation pit of Hujiamiao Station of the project ofXi , an subway line No. 3 is complex，and the full cover excavation method is used. Taking the deep foundation pit of Hujiamiao Station of tlie project of Xi , an subway line No. 3 as background，this paper studied the deformation of the subway station of the enclosure structure，the deformation law of the surrounding ground，and the deformation of the adjacent structures. The design scheme and monitoring results provided a basis for information construction of tlie subway station for the full cover construction. Research conclusions ：( 1) The design of the curtain piles，steel support and the military convenient girders played a very good effect in terms of suppressing deformation of foundation pit， the reasonable conclusion was verified by the monitoring data. (2) In terms of the bridge of Changle near to the edge of deep excavation pit， the grouting strengthening measure of bridge piles is reasonable and viable，and the safe operation of bridge has been ensured during the construction period. (3) Full cover digging subway station uses FLAC3D software to simulate monitoring data，the actual monitoring data were compared with numerical simulation results. Numerical simulation results are consistent with the monitoring results， to verify the correctness of the results. (4) The research results can provide a new reference value for the construction of tile loess region s otlier similar full cover deep station foundation.
