The invention relates to the technical field of bridge construction, and particularly discloses a special-shaped bridge positioning and paying-off method, which comprises the following steps of: acquiring coordinates of any two points at two ends of the same support beam on a construction site, and placing the coordinates of the two points on a drawing; the intersection point of the line segment and the bridge floor and the distances between the two points and the bridge floor are obtained; and carrying out lofting on site according to the intersection point and the distance. According to the method, the situation that lofting can be achieved only through multiple times of station transferring due to view shielding is avoided, errors accumulated due to multiple times of station transferring are avoided, the construction precision is reduced, the working efficiency is greatly improved by reducing station transferring, and the construction cost is reduced.
本发明涉及桥梁施工技术领域，具体公开了一种异形桥梁定位放线的方法，通过在施工现场获取同一支撑梁两端任意两点的坐标，并将两个点的坐标在图纸上；获得该线段与桥面的交点、两个点分别与桥面之间的距离；根据交点和距离在现场进行放样。本发明将避免了由于视野遮挡而需要多次转站才能实现放样的情况出现，避免了由于多次转站所积累的误差，降低了施工精度，通过减少了转站还将大大提高工作效率，降低了施工成本。
