description The invention provides a large-span arch bridge arch ring variable cross-section height calculation method. The arch ring cross-section height, needing to be calculated, of any position of a large-span arch bridge arch ring is defined as the ratio of the arch crown cross-section height to the power of the cosine of the horizontal dip angle of an arch axis of the cross section where the arch crown cross-section height is located; the power coefficient can be uniquely determined according to the pre-formulated section height of the arch crown and the section height of the arch springing; and thus, a new calculation formula is planned for calculation. Compared with a Liter formula, the calculation method is simpler, and the follow-up bridge body parameter calculation process is simplified; the height of the section of the arch ring at any position is calculated by using a formula provided by the invention; except that the heights of the sections of the arch feet and the arch top are equal, the heights of the sec
