Based on the non-destructive shaking table model test of a three-arch type underground subway station structure on liquefiable foundation, the strain response of the galvanized steel wire on the center pillar tested by optical fiber Bragg grating sensing technology and the strain response of the microconcrete corresponding to the position tested by strain gauge. The synergy effects of the galvanizing steel wire and microconcrete are analyzed quantificationally by Mann-Whitney U non-parameter test method. The results show that: The structure is at a elastic or minor damage work stage; Inspection coefficient P obtained by Mann-Whitney U non-parameter test method at the top and bottom of column pillar are all larger than 0.05 under different ground motion ;at the middle part of the center pillar ,the strain results obtained by fiber Bragg grating test technique are obviously better than by strain gauge.However, when under large electromagnetic interference ,or in areas with relatively weak signal , or for basis materials of small size, fiber Bragg grating test technique is more appropriate.
