Abstract：A brick-concrete residence building near the subway line was selected as the objective, sensors were set in each of the floor, the acceleration was monitored when the subway passing. The monitoring results were analyzed in time and frequency domain. The three-dimensional finite element model of tunnel-soil-building was established, the influence of subway vibration on the adjacent brick-concrete structure was studied. The results show that the vertical vibration response of the adjacent brick structure caused by the subway operation is maximum, and the main frequency is 40~80Hz, with the increasing of the height, the influence of low frequency vibration is obvious. The measured results are consistent with the simulated results. Through researching on the vibration response of brick-concrete structure caused by subway operation, the influence rule of distance，soil properties and tunnel burial depth on the vibration level of brick-concrete structure is explored, which provide reference for the building reconstruction and planning near the subway line.
