Stay cable tensioning construction method for engineering construction of cable-stayed bridge
The invention discloses a stay cable tensioning construction method of an engineering construction cable-stayed bridge. The stay cable tensioning construction method comprises the steps: solving the standard gravity of a stay cable; solving a real-time resultant force; solving wind power borne by the stay cable; obtaining a first coordinate of the first connection point and a second coordinate ofthe second connection point; solving a linear equation of a third straight line passing through the first connecting point and the second connecting point; acquiring the coordinates of the real-time point position of the wireless remote control trolley, and solving the real-time line point axle distance of the real-time point position; solving a standard line point axle distance; obtaining the maximum value of the axle distance of the standard line points to obtain the standard sag of the stay cable; and judging whether the stay cable tensioning of the cable-stayed bridge is qualified or not according to the real-time line point axle distance and the standard sag. According to the invention, the sag of the stay cable is monitored in real time in the stay cable tensioning construction process, and the stay cable is properly loosened and tightened according to the sag, so that the harm caused by overlarge deviation between the sag of the stay cable and a target value is effectively reduced.
本发明公开一种工程建设斜拉桥的斜拉索紧线施工方法，包括：求解斜拉索的标准重力；求解实时合力；求解斜拉索受到的风力；获取第一连接点的第一坐标和第二连接点的第二坐标；求解过第一连接点和第二连接点的第三直线的直线方程；获取无线遥控小车的实时点位置的坐标，求解实时点位置的实时线点轴距；求解标准线点轴距；获取标准线点轴距的最大值，得到斜拉索的标准弧垂；根据实时线点轴距和所述标准弧垂，判断斜拉桥的斜拉索紧线是否合格。在本发明中，实现在斜拉索紧线施工过程中对斜拉索的弧垂进行实时监测，根据弧垂对斜拉索进行适当的松紧，有效减少斜拉索的弧垂与目标值偏离过大而带来的危害。
