Abstract As the non-elasticity of slow concrete contraction distortion is shown by reinforcement meter, the concrete stress measured by reinforcement meter pre-buried inside main girder in construction of curved continuous bridge by jack-in method. This paper presents two calculation methods with deductiong influence by slow contraction distortion and special treating the influence on calculation of measured stress by slow distortion. The methods were applied in monitoring construction of one bredge and got good results.
