To deeply research the post-construction settlement of pile group foundation for Taizhou Yangtze River Bridge, the physical conception differences and the different application scopes of the two types of parameters were described by the viscoelasticity theory combined with rheological laboratory tests. Transformation relation between these two types of parameters was established theoretically. A formula for transforming viscoelastic coefficients to prory series was developed. According to the research results, the rheological laboratory test data were applied to the numerical analysis of the post-construction settlement by ABAQUS software. Calculation results reveal that the settlement of Taizhou Yangtze River Bridge will lasts for nearly 30 years and the post-construction settlement almost accounts for 20% of the final settlement, that it';s reasonable and feasible to calculate the post-construction settlement considering the foundation rheological properties for Taizhou Yangtze River Bridge with the above-metioned theories and methods. The method can provide useful reference for the same type bridge engineering.
