| Abstract: | The general structural design and flow process of the SPZ1300/48 bridging machine is discussed in this paper, with both the FEM analysis method for the girder's linearity diversification in the stretching process during the construction process and the principles for initial inverted arch setting described. The paper may serve as a valuable reference for the analysis of similar works. |
