Abstract
The Jin Shan Great Bridge is the longest concrete filled steel tubular (CFST) double-X-shaped arch bridges without wind braces in the world. This bridge has five continuous tied rigid-frame arches, with the maximum span length of 160 m. Based on this bridge, this paper numerically investigated the effects of the lateral restraint of soil to piles on the static response of CFST tied rigid-frame arch bridges. By comparing the calculated results obtained with and without the consideration of the effects of the lateral restraint of soil to piles for stress states and displacements of the arches and supported piers as well as the predicted stretching forces of the ties during the construction process of the bridge, the necessity of considering that effect was highlighted, and the way to consider it in the numerical simulation was specified.
