Beschreibung
Zusammenfassung:	The invention discloses an arch bridge arch rib hoisting linear control method, and relates to the technical field of bridge engineering structure construction.The method comprises the steps that measured values of linear control point coordinates of erected arch rib sections are obtained through measurement; according to the actually measured coordinate value and the theoretical coordinate value of the linear control point of the erected arch rib section and the theoretical coordinate value of the linear control point of the next arch rib section, the predicted coordinate value of the linear control point of the next arch rib section is determined through a rigid body motion transformation formula; and hoisting and splicing the next section of arch rib section according to the predicted value of the linear control point coordinate of the next section of arch rib. The problems that in the prior art, in order to correct errors between measured values and predicted values of arch rib segment linear control poin
